Quake Shareware CD: The DRM That Lasted 39 Days

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

Quake Shareware CD: The DRM That Lasted 39 Days

In 1996, id Software packed Quake's shareware CD with encrypted versions of their entire catalog, hoping players would call a hotline to unlock them. The scheme collapsed when hackers cracked it in 39 days, revealing that the unlock codes were merely proof of payment, not secrets. This deep dive explores the flawed TestDrive DRM, the QCRACK exploit, and the many bugs that made pirates' experience better than paying customers'.

The entire protection mechanism relies on security by obscurity.

    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.)

    "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.

    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.

    "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 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.

    As soon as I saw "Quake Shareware" in the title of this post, I thought "Pray to the one you will pay!" which was what appeared on the screen when you ran QCRACK.

    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!

    Surprised that it's not mentioned that the CD was also an audio CD with the Quake soundtrack..! https://en.wikipedia.org/wiki/Quake_(soundtrack)

    "Originally pressed on the same disc as the game, Quake was otherwise commercially unavailable until its release on vinyl in September 2020"

    Man, those CompUSA and Computer City pictures take me back. Spent too much time there (when the 7300 was my regular Mac, the CompUSA "Apple store" was my primary source of software). Probably still have some of those free Computer City floppies in a drawer somewhere.

More from this day
