Quake Shareware, a CD-ROM just a little too full

"For video game developers, the CD-ROM was an odd beast. The capacity far exceeded the quantity of assets they were able to produce. A few titles, like 7th Guest (1993) or Phantasmagoria (1995) introduced Full Motion Video (in a world where only part of the screen could be animated). "

------

The title that made me go out and buy a CD-ROM drive was "Wing Commander III", released during the holidays of 1994, a year and a half before Quake 1. This was peak "Silliwood", when games started to use FMV cut-scenes starring bankable actors like Mark Hamill. Games were still being released for the SNES at this point, so imagine the contrast!

In the age before wikipedia or ubiquitous internet access, it was also pretty amazing to have access to a multimedia enhanced encyclopedia. Storing large amounts of data was still a tricky thing. It would take a few years for CD-R's to arrive, and there would be a plethora of competing technologies like Zip drives. Looking back, it seems like computer technology was moving especially fast in the 90's.

The first CD-ROM gaming experience I remember was the Turbo Duo console from late 1991. It came with 2 disks of games. The first and primary disk contained Bonk I, Bonk II, Gates of Thunder, and a hidden Bomberman 3. The second disk contained a combined Y's I and Y's II.

The Y's combo really stood out. You have to understand that late 1991 was still the age of 8-bit NES gaming. This game was very much an 8-bit game that could have run on the NEW and yet it also contained almost DVD quality animated cut-scenes with top quality digital audio. It really felt next level, because the quality of audio was like a studio music album and the animation quality was better than what was on television at the time. It really felt next level compared to the NES.

To me the Saturn made the absolute best choice. The whole game's OST would be burned as audio tracks. I used to - and still can - just drop a game CD into an audio player and enjoy emblematic OST's like Daytona USA, Sonic R and many others in full 44100Hz 16bit audio.

I recall a few PC games did that too: Total Annihilation comes to mind: I also still own the physical media and still can listen to the OST that way.

PlayStation games had that too - not sure if all, but at least some of them. It was especially funny if the game disk failed to load as a game, but opened just fine in the PlayStation's built-in music player.

by Xirdus

8/19/2026 at 1:12:30 PM

> not sure if all

A fair amount, but far from all of them. AFAIR it was largely a technical decision with trade-offs; games that did it could offer CD-quality music, but wouldn't be able to read data from the disk and play music simultaneously.

by Cpoll

8/19/2026 at 6:31:10 PM

IIRC, the Quake 1 CD also had its OST as standard audio tracks

Quake 2 had it for sure, that CD spent as much time in my car as in my PC

8/18/2026 at 4:04:32 AM

Ah Phantasmagoria, that was an interesting case with my CDROM drive at the time, I think it was a Mitsumi one and there was a compatibility issue with specific discs from the 7disc bundle, so I buy the game, going home and start playing with some friends - that was common practice back then - we finish day 1 and I enter the 2nd disc and the FMV is choppy as hell! Try again and again and again and I assume the disc is problematic, so we go back to the shop and they ask what CDROM drive I have, I say Mitsumi and they tell me that it is a known issue with some drives and there is no workaround, so they offer to exchange the game for a different one, oh this "Harvester" game looks intriguing :) Fun times!

Myst was the CD-ROM killer game for me.

And yes, I think we both lived through the most rapid period of technological change (so far). Moore's law was real, the improvements each year were both felt and needed, and the software was coming along for the ride.

Quake was huge when it was launched - there'd never been anything like it. Of course, on my crappy Cyrix 6x86 and some similarly lame graphics card, I recall having to play it at something like 15fps. That wasn't great.

by epihelix

8/19/2026 at 3:46:03 PM

I too was in the Cyrix camp when Quake came out. My first video card was a Permedia 2. It ran GLQuake when that came down the pipe but not very well. The Christmas when I got my 3dfx Voodoo1 card was magical.

For very small values of newer. There have been two remakes of Myst since then.

When I was in university living in some crappy room at a friend of my parents, it was freezing and there were some transportation issues because of it, so I didn't go to classes and was bored around programming (I wrote Pascal those days for fun and profit), so a struggled to the closest shop to ask what's interesting; Phantasmagoria it was.

Good memories playing that one on that massively heavy monitor that was normal back then, under the blankets with ice on the inside of the windows and on top of the blanket.

I find it so funny that there are new games that are are smaller than Wing Commander 3 despite the 32 year gap. To be fair, they obviously pack their data very differently.

by ColdStream

8/18/2026 at 3:11:30 AM

Meh, in the early days of DVDs I recall a game that came with uncompressed 48kHz audio. Compress it to mp3 (which the game naively accepted if you had the correct Windows filters) and it fits in a CD.

by mook

8/18/2026 at 4:14:15 AM

Uncompressed audio tracks may have been necessary to get acceptable performance. e.g. GTA 1 came with some PCM tracks on the CD. If you didn't like them, you could pop in a different CD and get different music on the radio in-game. Playing mp3's was, in the early to mid-90's, actually pretty intensive. There were still a decent number of 386's around that could barely run a mp3 player in a Linux console-only setup. You needed a 486 or better to even think about playing mp3's with a full graphical OS running, and probably a Pentium before you have enough CPU left over for the rest of a game.

by beloch

8/18/2026 at 7:20:50 AM

For reference: I had a 486 DX2 66 MHz, and I played MP3s by decoding them in batch to PCM and then playing that as it couldn't really do that in real time. Perhaps only if you didn't do anything else and the MP3 was low bitrate enough and ideally mono.

by zorked

8/18/2026 at 7:53:57 AM

MP3 decoders have, thankfully, gotten faster since the 90s. But yes, a 66MHz is pushing it indeed.

8/18/2026 at 12:17:57 PM

Even as late as in 2008 I had such a slow machine that when I had to use NetBeans and I wanted to listen to music at the same time, I'd just play music CDs with headphones plugged into the headphones port of the cdrom drive :)

Nope, just a late 90s pentium running linux.

I went through a rough patch from 2002 to 2009 and couldn't afford new hardware, other than when I was finally able to get a second-hand laptop.

Before the laptop, I'd go visit customers with my pc tower and ask for peripherals when I got to their office, fun times. Well, not really, but I can laugh now ;)

Back in the day, my 200mhz Pentium remained just-barely usable while listening to WinAmp, but there was noticeable latency.

I never noticed any problems, but I did have the mmx version. It wasn't fast but never did the playback stutter , even with dreamweaver and several browser windows

by orhmeh09

8/19/2026 at 7:55:57 AM

Well, I looked it up and the game shipped in the early 2000s, and listed Pentium 266 as minimum requirements (Pentium 500 recommended).

I don't recall the 386 era and the DVD era overlapping that much…

by mook

8/18/2026 at 12:17:54 PM

CDROM and 386 would have been an odd combination though?

My 486 had a single speed CDROM but it only had a 500mb and a 100mb hard drive, so still wasn't playing mp3s

by benj111

by MBCook

And don't forget to engage your "TURBO" button, to make the playback slightly better!

by stevekemp

8/18/2026 at 7:47:03 AM

The turbo button was always on, or it should be. you would turn it off to downgrade your pc to run at the speed of the original IBM PC in the mostly vain hope that whatever old game that was programmed for that exact speed would start to run right. It was slightly be fore my time(we had a 286 with the button, but I was to young to be curious about it) Would the pc take the speed change without problems or was it best to reboot? I sort of hate whatever marketing genius figured out to label it "Turbo" instead of "Slow" But they definitely earned their bonus.

The real weird one from that era was the 7 segment led MHz displays that were popular in the 386/486 era. It was weird because the the chips could not change speed in the first place. And I don't want to say every system was like this, but every one I ever saw was set by a set of static jumpers or a dip switch. When you upgraded your cpu you put the little sticker that came with it on the chassis and changed the jumpers, they served the same purpose.

by somat

8/18/2026 at 12:15:45 PM

The way I remember the turbo button it just halved the clock speed when not depressed, but it didn't bring it back to the original IBM PC's speed.

I do remember using it to make older games play less bad, but, as you say, this rarely worked, I think precisely because the speed was never the original one (I don't remember the clock speed of my first PC, but the first one with a turbo button ran at 33 MHz which I'm sure is a lot more than twice the speed of the first one; seems closer to 8x from what a quick search implies).

by fipar

8/20/2026 at 2:45:08 PM

Yes, our first family PC was a 386 that we could slow down from 33 to 16 MHz with the Turbo button. It even had the segment display to show the current clock rate.

I knew what it was for and had some old games that ran too fast, but from what I remember, in most cases 16 MHz was still much too fast, so I didn't use the button much.

I think it was no problem to switch Turbo mode on and off in the middle of running software.

by Anamon

8/18/2026 at 5:09:09 PM

It was more than half (depending on age). I thought it always took you to 4.77 MHz to match the original 5150.

Sure. I never understood it as a kid. The fact it slowed your computer always confused me since I didn’t realize it was on by default.

mp2's files were almost usable on 386 but they used tons of space.

by anthk

8/18/2026 at 5:17:17 AM

When Metal Gear Solid 4 released on Ps3, they used uncompressed audio. I think part of it was just to show off how much storage Blu Ray had.

The game Titanfall on PC has the audio in it twice, compressed and decompressed. The decompressed was for machines with dual core or less so that there was enough overhead to keep the game running.

by ColdStream

8/18/2026 at 11:28:52 AM

The video game Uru shipped with the sounds as ogg files. Post installation they were decompressed to wav files, I'm guessing so that they can squeeze some more performance out of the game

by 4thguy

8/18/2026 at 5:29:51 PM

> Post installation they were decompressed to wav files, I'm guessing so that they can squeeze some more performance out of the game

Maybe, but there could be other reasons.

In a former life I briefly worked at a game developer, and the PC port of a game we shipped did the same thing. The reason I got was that the assets were just barely too big for the game to ship on one CD-ROM and going to a second disc was going to cost too much. The solution was to encode all the sound assets into .ogg (because it was free and unencumbered) to put on the disc and then convert them all to .wav post-install because the in-house engine couldn't play .ogg files and there was no time to add support before publishing.

by basscomm

8/18/2026 at 7:24:09 AM

Why would it play the compressed version if it had the decompressed audio right there though?

by zorked

8/18/2026 at 8:21:39 AM

Because with lossless compression you can save a lot of storage space without losing any quality. You are thinking about lossy compression.

by williebeek

8/18/2026 at 12:01:05 PM

I think you misunderstood his question.

Given two files, a compressed file which must be uncompressed to play, and an uncompressed one which does not require extra processing - why would the game ever bother uncompressing te compressed file when the same data is already available uncompressed?

There's no true use case for that that I can see.

by fizzbuzzbarbazz

8/18/2026 at 12:19:43 PM

With hard disks, I could see reading the compressed version from disk and decompressing giving you the bytes faster than reading the uncompressed version. With SSDs that advantage likely went away.

by Uvix

8/18/2026 at 2:38:03 PM

Yep. If you had the CPU overhead available, you could speed up your entire computer by enabling full-disk compression and then defragmenting. It's difficult to accurately describe just how slow it was to move data to and from a spinning platter over a PATA interface.

by unregistereddev

8/18/2026 at 12:21:00 PM

I would guess to save on installed size?

by benj111

8/18/2026 at 1:39:56 PM

It's not about size or file count or disk space consumed. The question is about why would you require the extra overhead of playing the compressed version which involves decompressing it on the fly in some way, versus just playing the already decompressed version.

In this case it was stated that both the compressed and decompressed versions live side by side. So there is no install size saved.

by RobotCaleb

8/18/2026 at 5:05:35 PM

The OP stated

"The game Titanfall on PC has the audio in it twice, compressed and decompressed."

'has it twice' could just be on the install media, and compressed/ uncompressed chosen as a trade off between install size and performance.

Anyway searching around the OP seems to be misrembering. Titanfall seems to be well-known for 35gb out of the 48gb install being uncompressed audio. I couldn't find a reference to it also having compressed audio also.

by benj111

8/18/2026 at 5:31:09 AM

They're doing that with Blueray games now, writing gigabytes of uncompressed audio for no particular reason other than to use up space and sucker the occasional audiophile.

For some bizarre reason when upgrading from the family Mac SE to a Quadra, I had an idea in my head cd-rom drive was unnecessary. Thankfully in less than ten years I was proven correct.

Obviously I didn’t play enough games.

I did exactly this thing when I was a broke teenager. The files in my ID1 directory that I shuffle around from computer to computer to this day came from that disc 30 years ago. (I still have the disc, but not the case.) I did, however, purchase Quake II and III when they were released. And many years later bought Quake on Steam. I think they got their money's worth from me after all.

(There were some who believed that making the shareware disc easily-crackable was an intentional stroke of genius. It got people who couldn't afford the full retail version to buy the game and expand its popularity. The argument being that $10 was a fairly ludicrous amount of money to pay for a single shareware game. Shareware CDs tended to be $5 on the high end, or free with most computer/gaming magazines.)

I doubt it. I would believe that the id guys weren't too choked about the lost revenue after the fact, but the business guys probably believed the scheme would work (especially since they contracted a company that said "yes, this will work").

Aside from that, the shareware cd was incredible marketing - the digipak cd case was the kind of art and paper construction that nin was using on their discs (like the Broken EP), and the disc itself has nice art with the four logos in cardinal directions. I bought a copy of the registered disc from ebay years later and it's in a jewel case with really crappy artwork vs the shareware version, it was a surprising disappointment.

by ryanjshaw

it would have been like 520 hours to download 500mgb. Assuming it didn't break at some point.

That was pretty tough in that day and age. Especially from pirate sites.

mIRC had some good servers but getting someone to keep a direct connection with you for that long was problematic too.

And then if you didn't have a dedicated phone line for the modem...

by virtue3

8/18/2026 at 7:07:57 AM

If I remember correctly, actual pirated copies would have been maybe tens of megabytes, since they didn't include the CD audio. But that would still have been a hefty modem download.

by Lorkki

8/18/2026 at 1:51:30 PM

The common pirated version of Quake was a 20MB pre-release leak that had oodles and oodles of minor differences to the final version. All of the actual levels themselves are playable and completable. The funniest differences are a mean trap that was removed from the final E1M1, and E2M6 still begins with the eponymous oubliette, banished from official releases until 2021 (!).

by skhr0680

8/18/2026 at 2:11:03 PM

People were still replacing their 14.4k modems with 28.8s in 1996. I remember seeing the Quake 15 x 1.44 zips on local BBSes, which would've taken at least 3.5 hours over a perfect 14.4 connection so definitely a daunting phone line tie-up for the average kid (I had the CD.)

Oh, but that's why you went to the computer lab of your uni - those machines were on a 10mbit LAN and had a decent connection to the internet!

Although you still wouldn't download a CD, simply because... you wouldn't have been able to take it home with you! Hard drives were in many cases smaller than a single CD. Anything more than a few 10s of MBs would have been considered excessive.

by haspok

8/18/2026 at 10:58:13 AM

Connecting to office LANs and going on the internet was a magical feeling back then. The speed coming from a 56k dialup was jarring. We'd have network games of Quake (rocket jumps included) and watch Real Player versions of grainy South Park early episodes at er, lunch. Good times.

by _joel

8/18/2026 at 5:43:53 PM

More than the raw speed was the fact that the error checking, buffering, and compression on dialup added anywhere from 150-400ms to your ping RTT. You could disable a lot of it, but results could be mixed depending on the quality of your lines.

by hylaride

well, if dialup cost more than just buying the game, it makes sense to buy it rather than pirate. also, if you care about audio then you'll get the cd, becuse downloading 400MB of audio over dialup isn't fun.

compared to that a crack is just a single binary.

by sznio

8/18/2026 at 8:16:20 AM

Dial-up cost will be discovered later by upset parents, and you already have all your nice pirates games, which you would need to pay upfront with your own pocket money (if that existed).

But in any case physical copy + crack was the best solution at the time.

This strategy makes sense in developing markets. People might be too poor to buy your game right now so you distribute it for free hoping that in the future they will get rich and then they'll actually buy your newer game.

It’s worth getting the Quake shareware disc for the NIN soundtrack. Official track names are now available following the vinyl release a few years ago. This is the only CD release of the soundtrack. Just don’t forget to skip track 1.

by jonhohle

8/18/2026 at 2:11:51 AM

> Just don’t forget to skip track 1.

There is very slightly more to it than just the mixed-mode sessions: the audio tracks on the Quake CD were mastered with pre-emphasis, so your ripper or player needs to apply corresponding de-emphasis EQ in order for them to sound correct. 1996 was actually a strangely late year to find any CD mastered with pre-emph; it was mostly an '80s thing: https://www.studio-nibble.com/cd/index.php?title=Pre-emphasi...

On top of being a technique that had fallen out of common use by that time, Quake has the pre-emphasis metadata flagged in the subcodes but not flagged in the TOC, so some software players/rippers like (annoyingly) Exact Audio Copy won't heed it: https://wiki.hydrogenaudio.org/index.php?title=Comparison_of...

Here's a side-by-side comparison — my EAC rip of my MacSoft version of Quake (left) alongside the output of `sox_ng deemph` for the same file (right): https://i.ibb.co/9m18CSsk/Emi-2026-08-17-18-52-48.png

And if you're curious, here's the pre-emphasis subcode channel Q flag and pre-emphasis frequency response as described in the Red Book standard, and sox_ng's code for undoing it:

― https://audio-union.com/wp-content/uploads/2023/02/Red-Book-...

― https://audio-union.com/wp-content/uploads/2023/02/Red-Book-...

― https://codeberg.org/sox_ng/sox_ng/src/branch/main/src/deemp...

Although if someone has been unknowingly listening to the pre-emphasized tracks for thirty years, maybe the ‘incorrect’ one is what sounds right to them? :)

IIRC, it's actually debatable if the pre-emphasis flag is supposed to be set. I don't remember the exact details anymore, but I think it was discovered that there multiple releases with bit-identical audio tracks, but some of them have the flag set while others don't. They can't both be correct, because the audio data should've changed if the emphasis was removed.

by protimewaster

Make sure that it isn't a case of the software you're using to inspect the disc intentionally looking the other way with regard to that flag.

> Quake has the pre-emphasis metadata flagged in the subcodes but not flagged in the TOC, so some software players/rippers like (annoyingly) Exact Audio Copy won't heed it

I learned that this is an intentional deficiency in EAC: https://forums.stevehoffman.tv/threads/eac-not-detecting-pre...

> For a short while, up to version 0.95b3 [in 2004], Exact Audio Copy had a manual function to actually scan the audio area of the disc also [talking about subcode channel Q versus the TOC] to find if tracks used pre-emphasis. This was removed due to some perceived legal threat. Now, basically, a standards-compliant disc that doesn't use the TOC kludge won't show "pre-emphasis"

And sure enough, the Red Book standard mentions usage of the other three flag bits alongside the pre-emphasis flag: https://audio-union.com/wp-content/uploads/2023/02/Red-Book-...

The adjacent bit is “copy prohibited” versus “copy permitted”, which is not a piece of metadata I knew Compact Disc had. Makes a lot more sense why EAC would remove that feature in the legal climate of the P2P era, because to look for one flag also must look for the other, and this way it's out of sight and out of mind and Gee Your Honor We Didn't Know You Couldn't Do That if someone uses EAC to rip a “copy prohibited” disc. I wish I could get this feature back in 2026 though :p

I actually remembered more about this after my initial post. I ended up with two copies of Quake (one is the original shareware release and one is a later release of the full game), and one of them has the PRE flag set in the TOC and the other one doesn't. Now I'm wondering if I ever checked the subcodes for the one that's missing the flags in the TOC. I'll have to dig it out sometime and check.

I did verify that the audio is identical down to an offset, though, between the two.

> The adjacent bit is “copy prohibited” versus “copy permitted”, which is not a piece of metadata I knew Compact Disc had.

I wonder if any equipment ever actually used those other flags for anything?

by 986aignan

8/18/2026 at 12:43:22 AM

In each sector 2048 of the data bits are just bits, but each data sector also includes 12 bytes of sync, 4 bytes of metadata and 288 bytes of ECC that are not really controllable (if you want the disc to be readable). Then there’s the ISO 9660 on top that will impact the first few sectors. If you have a single file (say a zip/tarball/rar, image) you could limit that. Assuming you could mask the noise from the ECC at 75hz it might be possible.

I remember I had the CD but rarely used it because having to pop in the CD just to play the game was annoying. So, I mostly played it without the sound track. Also, I never was that much into nine inch nails. Just not my genre. But my memory of the game is that it was fine without music.

"The CD was announced[4] on July 3, 1996 and released on August 30th[5]. The hacker group GNOMON released Quakecrk.zip only 39 days later[6]."

While not being familiar with the Windows side of things, I did frequent the a.b.m.a newsgroup being a broke student. It was always impressive to me to see how quickly someone would post a binary before the crack was posted. I remember one app I was very interested in posting on Friday, and the crack available when I checked back on Monday. Even apps that needed a physical dongle for the ADB port were cracked and not just the apps that needed a key typed in to unlock. Later, the apps that would clone a USB dongle came along, and one software company that used USB dongles actually advised using this tool when we started running their software on Blade servers that did not support adding 24 USB devices.

by dylan604

8/18/2026 at 6:37:39 AM

I did reverse engineering as a hobby in my teens. The method for 90% of cracks back in the day boiled down to:

1. Launch the app.

2. Trigger the "not registered" screen.

3. Search for the string in the binary.

4. Search for code that references the location of the string and squint hard until you spot the "check if CD-key is valid" section.

5. Patch the final opcode from "jnz" to "jz". If you felt fancy, reverse engineer the checking algorithm to create a keygen instead of a patch.

Anticracking methods became mainstream in the late 90s, but they weren't very sophisticated and most amounted to obfuscation.

Long live +ORC, +Fravia and CracksLatinos.

This was me as well. +HCU and searchlores.org were so much fun. The coolest thing I remember was the hash-maze but I couldn't find it again. I saw Fravia live in 1999 :D

Switching 0x74 to 0x75 and vise versa lead to me ordering the free Intel books and diving into assembly and osdev for a while. There was something zen-like wading through disassembled code with a complete beginner mind and looking for patterns. This and reading Phrack around the "Smashing the Stack for Fun and Profit" times are probably my favorite memories related to computing because I only had a very vague understanding of what was going on mixed with a sense of "wait you can do this" and a lack of readily available information.

I remember old games shipping with huge lists of codes on paper. Paper made, on purpose, too big for an US legal/A4 photocopier. And moreover the codes would be using "light blue characters on slightly less light blue paper". Very annoying for casual piracy (as in: copying your neighbor's version of the game).

Siemens for some software uses a license system that uses "secret" files stored on "dongle" that is just USB stick, and software that manages copying to hard drive etc.

I have heard of several cases where Siemens technicians and support staff would use a well-known "crack" (actually more of a keygen combined with license file manager) or guide customers how to obtain and use it...

> By June 1996, after three years of hard work, id Software had completed their next title, Quake. As for their previous title, they were going to release both a shareware version and a full version of their game. Since it used a mere 22 MiB of storage, people at id Software had the idea of leveraging the remaining capacity of a CD-ROM. Why not include encrypted versions of the full id catalogue of games? Not only this would cut out the middlemen, it would give instant access to gamers with a simple phone call and a credit card.

That wasn't a new idea at the time. In 1994 Apple distributed a "software store" CD-ROM called Software Dispatch that implemented the same idea: https://68kmla.org/bb/threads/apple-software-dispatch-from-1.... The thing was full of demos, and if you wanted to buy the full version, you just had to call some number to get an unlock code.

I think I had at least one other CD-ROM that implemented the same concept. I'm sure there were tons of others.

Those photos of the inside of CompUSA are just stunning. Bright sodium lighting, not a dim dank cave (one of the benefits of CRTs over modern OLED screens and their color range from black to slightly-less-black). Colorful packaging everywhere (this was before fun was made illegal in 2012). Big signage, so you know where things are (the idea of a customer knowing where to find something without being diverted to an antivirus upsell by a "helpful" "associate" didn't bother MBA CEOs back then. Nowadays the idea would cause them them to spontaneously combust).

> The phone number is still active today. However you don't reach the unlock center since CompUSA went out of business. The Superstore chain closed between 2007 and 2008. Instead of an unlock operator we get an automated message to sell us elderly stuff.

Reps would also shower you with free or discounted stuff, I recall having a good friendship with a Creative Labs who rigged contests and gave away shit constantly. Lots of free software to be had as well. It was effective though because I happily and aggressively shilled for the companies hooking me up.

That issue of the magazine sold out pretty quickly once it became public knowledge. Corel issue a statement that replacing the files doesn't make it a legally licensed copy. I'm sure many people cared.

It was actually reasonably common around the mid 90's for game CDs to have their music as audio tracks on the CD.

I guess there was a point when CD-ROM was the target format anyway but game content hadn't necessarily grown to fill it yet. Having the CD drive play the audio directly (it could be directly connected to the sound card) with no decompression or software processing required probably saved some CPU cycles as well.

I think at least half a dozen games I had around the time did that. Of course most of the soundtracks wouldn't be interesting enough on their own.

by Delk

8/20/2026 at 6:48:40 PM

It was routine for preteen and teenage me to put any game CD or game magazine coverdisc in the Hi-Fi CD player at some point, and see if the track number indicator would show anything higher than 01. It was definitely quite common. Some that I remember are Grand Theft Auto, Carmageddon, Alone in the Dark 2, Rayman, Little Big Adventure 2, Tunnel B1, 7th Guest, The Dark Eye...

The music was made interesting by the sheer novelty of being able to listen to it that way, and get a bit of the game to enjoy even after the parents decided computer time is over =D

by Anamon

8/18/2026 at 8:02:32 PM

Did the early proprietary CD-ROM interface cards that shipped in "multimedia upgrade kits" and on sound cards even support DMA?

I know both DMA and PIO-only SCSI HBAs existed at the time, but I'm not sure about the proprietary interfaces that were more common for consumer CD-ROM drives.

by jasomill

8/19/2026 at 9:16:15 AM

Very firsts Philips/DEC LMSI controller did DMA https://github.com/AkBKukU/CM153-Repro https://github.com/AkBKukU/CM153-Repro/blob/main/EDA/ISA-Car...

Panasonic (MKE) was pure pooled PIO and didnt even support Interrupts. Sony and Mitsumi do have DREQ/DACK pins so most likely did ISA 8bit DMA. ISA DMA is pretty terrible and slow (4.7MHz clock, steals CPU cycles for the duration of the byte transfer), barely enough for 2x CDROM. IDE PIO is better on 286 and up than ISA DMA thanks to nice dedicated REP INSW. Taking into account ISA limits transferring one CD sector should take no less than ~700-1000us.

While ISA SCSI and VLB controllers could do DMA, they rarely did with ISA 16MB memory limit and VLB compatibility worries. The one VLB IDE controller dlaiming to do DMA, Promise PDC20630, does MWDMA2 to the drive but with CPU manually pooling IO pins on the other side, total waste https://www.vogons.org/viewtopic.php?p=1323789

TLDR: Talk of enabling DMA for your HDD and maybe even CDROM became common only somewhere around 1996, a good year into Intel shipping busmastering IDE controller in PIIX on Pentium boards (430FX and up). You had to put devices on separate IDE channels and hope everything is compatible and works.

How would the challenge/serial have worked if implemented correctly?

Since the challenge rotate every 5 minutes, there must be some way for a user to enter against an old challenge, right? Else they call, get a code and nothing.

But even with that out of the way, the decryption key must be the same across all discs, since there is only 1 master disc.

So the challenge/serial must combine to create a decryption key, which can be shared across users.

by wodenokoto

8/18/2026 at 9:59:32 PM

IIUC the rotating challenge actually didn't have anything to do with the key, it was a red herring. The actual decryption key was just a function of the fixed serial number or something like that.

by andai

8/17/2026 at 11:37:48 PM

Yes, the game just played it as a regular CD. In fact, if you put a different disc in the drive it would play the tracks from there instead. There were also console commands to change the track, stop the music, loop, or even reload the disc information if you needed to refresh it after swapping CDs.

by fullstop

8/18/2026 at 12:43:23 AM

Yeah, and I remember if you didn't have the audio cable that went from the CDROM into your sound card, you would never hear the tracks. It wasn't your computer decoding the music, the CDROM drive was simply doing the decoding, and passing the audio out into a CDROM input (just a line-level audio signal) on your sound card.

by olyjohn

8/18/2026 at 1:12:18 AM

I'd forgotten about those little cables. If I recall correctly, they were small round cables, with maybe four conductors and a little flat connector with a clip?

by jaredhallen

8/18/2026 at 1:40:14 AM

4-conductor audio, generally.

Later on there was a generation of two-conductor cables that used SPDIF/PCM Audio instead of analog audio for better fidelity.

by indrora

8/18/2026 at 12:06:34 PM

Audio tracks and WAV/AU files weren't actually decoded, but straightly send to the sound card as bits. That's it, a command like

        cat file.wav > /dev/dsp
Would just work under Unix (/dev/audio under plan9/9front)

Thus, making a function for Quake to read the CD bits to the sound card would create almost no CPU usage, even less with DMA.

by anthk

Wouldnt you need different master-CDs for doing that, as AFAIR when pressing CDs commercially, you usually have exactly only one master?

by KellyCriterion

8/17/2026 at 11:19:54 PM

Maybe have n versions of the CD (maybe 16, or 32), so there are n decryption keys. When the buyer recites the code over the phone, the program run by the salesperson can identify which key is used based on the number.

The hacker groups would be a little frustrated trying to find all of the different CDs.

by netsharc

8/18/2026 at 12:03:40 AM

The multisession standard actually afforded the possibility of CD-PROM; a hybrid disc with a pressed read-only session followed by a writable section. It was only used for Kodak Picture CD (not the same as Photo CD) to hold software in the pressed session. It also apparently standardized a magneto-optical hybrid that never made it to market.

by kevin_thibedeau

8/18/2026 at 5:21:30 AM

by notpushkin

It's still not possible. You would need to make a unique master for every individual unit.

by vanviegen

With CD-Rs it was already possible in the mid '90s, if we're talking mass production. CD-Rs are a little more expensive to produce, but not much more so. A slight concern is that readers of the time might not have been able to read the discs, because CD-Rs are not quite as reflective as CD-ROMs.

by fluoridation

8/17/2026 at 11:22:28 PM

You would need some sort of hardware serial number system for PCs and a whole security infrastructure to verify that the serial number being used for the unlock wasn't faked. Then you could do per-PC unlocks. I'm not aware of anything like that being widespread back in the Quake days, though these days every computing device you own probably has a unique ID burned into ROM somewhere.

This screw up ended up costing id Software millions in sales. With the Doom franchise they only included the first episode in the shareware version. But to save a buck I guess they decided this was better than mailing a second CD with the full game on it. Then doubling down on that greed by putting their entire game library on the disc. This is right about the time John Romero and John Carmack parted ways, can't help but wonder if this debacle played a role. And by all accounts Quake's development was painful, so imagine this happens after going through hell getting a game out the door.

> With their capacity of 640 MiB (three times the storage of PC HDD at the time), CDs allowed enthusiasts to step into a world of multimedia, made of high-resolution 640x480 256 colors palette-indexed photos[1], VOC soundtracks, and play with Video For Windows butter-smooth 12 fps 240x179 videos[2][3] lasting up to several seconds.

Deliciously worded, and highlights how far we have come since then.

Man, if I were id, I'd sue the hell out of Testdrive for selling me that broken security system...

by netsharc

But it sounds like it wasn't Testdrive's fault; iD implemented it incorrectly. Their phone support weren't issuing the decrypt code, just a simple checksum:

> Described as is, there is no flaw in this process. The secret seed comes from the unlock server, tied to a CHALLENGE/SERIAL that could not be reused. But the hacker team GNOMON found a way.

> The QUAKE unlock program FLOW.EXE that ships on the CD is capable of generating the SERIAL from the CHALLENGE on its own. All it does is check that its own locally-generated SERIAL and the SERIAL entered by the user match! The entire protection mechanism relies on security by obscurity.

If the phone support issued the decrypt code, you could just replay that same code for every CD stamped from the same master.

If phone support issued an encrypted decrypt code that could only be used with your challenge code to decrypt the decrypt code, replay wouldn't be as trivial.

Every CD is identical, so no matter how iD went about this there's only ever one decryption key (per title, I assume) and those keys must either have been encoded in iD support's response, or already stored on the CD. TestDrive sold iD on the notion that the process was too hard for hacker groups to reverse engineer, and it wasn't.

There was some replay protection as described in the article, but in the end the system was flawed enough that it didn't matter.

Am I reading this right, and was only the file header encrypted? Also, wasn't ID the company that did not use serials or other DRM? Maybe that explains their naivite, maybe they underestimated how easily games get cracked.

Not sure about the early days - I got a Quake II CD in the early 2000s that didn't need a CD key. Doom 3 and Quake 4 required CDs, at least at release, but after a little while no CD patches were released.

$55 ($9.95 CD + $45 activation) in August 1996 = $116 today, per the BLS inflation adjustment calculator.

Gold was ~$400 back in 1996. Now it's ~11 times that.

An expensive game however you gib it.

Is it really fair to call these such algorithms "security through obscurity"?

By that logic, wouldn't real symmetric crypto also be considered the same, since it's still just math that similarly swaps the data with other bytes, based on an "obscured" password or key?

by ranger_danger

8/17/2026 at 10:58:59 PM

The obscured part was pretending the unlocker needs external information

by _def

8/17/2026 at 11:08:34 PM

I guess they could have done a public/private key pair in 1996, but doing that over a phone call was going to be painful. A simple password read over the phone and verified by the software was the best solution at the time.

Mind, this was also intended for a world where internet connectivity was not to be expected. The majority of PC owners were not online.

by chungy

8/17/2026 at 11:19:31 PM

How would your scheme work? You use RSA to encrypt the entire thing? Or you use it to get a key for a block cipher and then use that?

I feel like either way, you'd need the key to be different for every CD, otherwise you could just share the shared key. But if the encryption of every CD is different, why not just share the block cipher key directly? They can have a list of CDs and the associated key(s).

What additional security or functionality does an RSA like step add here?

Also the same way we got viruses, long before anyone I knew had the Internet.

If I ask you to pass on a message from me to someone else, and the message is encrypted using a symmetric key known to me, and to the recipient, but not to you, there's no security-by-obscurity in place.

If I ask you to pass on a message to someone, and the message is encrypted using a symmetric key known only to me, and I expect the recipient to be able to decrypt it because he knows that the key is written on the back of the paper, that's security by obscurity. You're just as able to do the decryption as the intended recipient is; I'm just hoping that you won't realize that.

by thaumasiotes

8/18/2026 at 2:52:26 PM

But all parties are able to bruteforce the key, it's still just math, still obscured. The only difference is how complicated the math is, and how long the attack takes.

Changing from a simpler substitution algorithm to a "real" crypto cipher IMO is still just as symmetrical, and still technically obscurity, only more complicated this time.

by ranger_danger

This isn't true, and you should be well aware of that.

by thaumasiotes

8/18/2026 at 6:05:37 AM

I think it is fair, as all the released CDs are identical. So all the symmetric keys used to encrypt the data are also necessarily identical.

Okay, I haunted CompUSA in my teen years and I purchased my first 386 system there. So the photograph included in this blog seems bona fide.

Except their logo or name was never "Compu USA". Where in the world did they get a store hung with signs that all say "Compu USA"? Is this some Mandela Effect that has me in its clutches? The business was definitely never named or branded that way. I did my Wikipedia and Bing Images research. There are no serious search hits. Gemini is giving some truly b.s. explanations that I do not believe.

Is this a concrete example of a USA store tolerating mis-branded signage... inside their own store? Or is it some third-world knockoff? The merch on the shelves, the bros shopping for themselves, the tie-wearing salesmen, they all seem totally legit. What kind of big-box computer store lets that happen to their signage?

by brcmthrowaway

8/18/2026 at 9:30:12 AM

Every game separately encrypted then compressed into solid archives. Pressed in a way every game lands on different precise height of CD, padded before compression if necessary so it takes enough space on CD. Separate machine burning tiny holes in CD from the back, but not so tiny that CIRC could fixes them. At least one hole per file.

Install locates the damage and gives you code encoding locations. Over the phone You receive ECC code. No more magic keygens, pirates have to distribute whole multi megabyte games.

by tetrisgm

8/19/2026 at 9:33:59 AM

Sure, but the question wasnt about solving world hunger, wars and global piracy :) Its a solution for limiting pirate-ability of this particular CDs contents.

Encode data in a way short ECC code dictated over the phone is enough to reconstruct one missing sector (2KB).

by rasz

8/18/2026 at 5:55:44 AM

COD:BO7's single-player uses dedicated servers. Terrible, yes, but that's as foolproof as it gets when it comes to piracy. They also probably did this to combat all the 'services' offering to unlock camos/cosmetics that you'd normally have to grind for; players would give someone their credentials (probably stolen later and sold to cheaters) and the person on the other side would then use a hacked client to trick the backend into thinking they completed all the challenges. With a server-side campaign, that probably got much more time consuming, I reckon.

by brcmthrowaway

8/18/2026 at 4:22:27 AM

I think most (all?) Steam games link steam_api.dll (or something like that) which somehow figures out the running Steam process and thus the Steam ID, and then does a HTTP API request to check that you own the title.

Like 15 years ago Steam launched CEG (Custom Executable Generation) - I remember reading a write-up a while ago, but each user had a customer launcher generated on install I think, and I think there was an extra segment put into the .exe file and that was put to use somehow, though I don't know if CEG is still a thing.

by jamesfinlayson

8/18/2026 at 4:26:12 AM

The ownership check you are referring to is a local check. There is another check (involving EncryptedAppTickets) which is not local, but far fewer games use that.

CEG is long dead/was broken immediately in a pragmatic, automatable way.

by select1

Kind of sounds like the low‑background steel [1] problem all over again.

I have a rather badly written tool [2] I made about 5–6 years ago. If you connect it to your Google Custom Search Engine (along with the appropriate CSE keys), you can quickly search, copy, and download images from before 2022. It also has a ban list so you can filter out Shutterstock, Alamy, and other heavily watermarked sources.

The app is a hot circle of garbage code, but it might still be useful as a starting point.
