(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.
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.

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.
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 long 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
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? :)
There's millions of such CDs in the wild, both shareware and fully purchased copies.
I always wondered why Final Doom didn't unlock with QCRACK - I always assumed it was a bug with the keygen, never realized it wasn't possible to purchase it from the disk at all!

Later on there was a generation of two-conductor cables that used SPDIF/PCM Audio instead of analog audio for better fidelity.
It was not possible to manufacture at the time at scale.
The hacker groups would be a little frustrated trying to find all of the different CDs.
> 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 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.
I'm pretty sure I bought it for $6.66
Why do we think that CCITY is a code for Computer City and not Circuit City?
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?
Mind, this was also intended for a world where internet connectivity was not to be expected. The majority of PC owners were not online.
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.
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.
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?
