Dungeon Master - the classic 16 bit dungeon crawler that defined a genre was one of the best ever games for the Atari ST and Commodore Amiga. Released in 1987 by FTL (Faster than Light) it saw many ports to different systems including the Sharp X68000, MS-DOS, Apple IIgs, Super Nintendo and more.
It also had one of the most devious floppy disk copy protection schemes ever created. In an age where most games were cracked in a matter of hours, FTL's clever protection took an entire year to crack with many attempts to defeat it, resulting in failure over and over again.

  • Now that is what you're great at. Talking about vintage machines and copy protection.. It's what brought me here and makes me come back. Old gear is still best for true gaming experience. Meh PS5 and X-Box. Too many videos about it with little news. Greetings.

  • Your comment in the video reminded me of my friend's pirate copy of Carrier Command on the Amiga. It seemed to play fine for 15-20 minutes then the sound started to go eerily distorted and the game would eventually crash. I did buy the game for PC and played it for hours in glorious CGA. I remember it came with the theme tune on cassette.

  • A long time ago my parent's bought me an Amstrad PC1512 as I was going to do my A-Level's at Grammar school and they were told that was the computer I needed (actually it wasn't as they were using RM Numbus's, and I was lusting after an Amiga 500 so ho hum). Anyway as I recall I made a copy of one the games I had for it (I forget which) onto another 5 1/4 disk, and when attempting to play the game it seemed to know it was a copy as it made a racket as if it was trying to hammer the disk with the read head. I quickly whipped out the disk and never dared try it again. I always wondered how that worked as I never experienced it since.

  • You normally could NOT copy the manual, as it would be black text on dark red paper, or whatever messed up a Xerox back then.

  • Small clarification: NDOS disks weren't necessarily just for copy protection. Sometimes alternate disk formats were used just to squeeze more data onto the disk, perhaps at the expense of redundancy/reliability.

  • As an Amiga owner back in the day, I‘ve had to wait a full year for Dungeon Master to get ported from the Atari ST. After drooling over the reviews in all the game magazines for so long, I never even dreamed of pirating my most anticipated game. Just rushed out and bought my retail copy on day 1 and sure enough, it became my favorite game on the Amiga.

  • Back in the 1980s I used to crack software for the Apple ][, then later on also for the Macintosh until Apple eventually switched from 68xxx to the PowerPC processors, then it became more trouble than it was worth. The first copy protected program for the Apple ][ that I can recall was PFS. It wasn’t actually copy protected except for the fact that the original disk had no write-enable notch. So if you booted up a copy that was not write-protected, then the software would erase the disk. Unfortunately the same thing would happen to your original disk if you had a misadjusted or bad write-protect switch on your apple disk drive. Since most of the low-level disk access was done in software and used very little hardware, it was fairly easy to implement copy protection techniques on the Apple ][. Early on just changing sector address and data header ID bytes was enough to cause normal copy programs not to work. Also programs would load data into zero page and the text screen buffer, and breaking out would cause loss of code when the screen scrolled or cleared. So for disks I couldn’t copy I had to find ways to capture all the code out of memory and be able to reload it all into the correct places and restart operation. Early on there was a nibble copy program written by Steve Wozniak which I was able to modify to copy different disks. Then followed a number of commercial nibble copy programs like Locksmith, which just read and wrote a whole track worth of data without trying to parse it. Next developers started using other techniques like half-tracking where the original disk actually had data written between where the tracks would normally be positioned. Then the nibble copiers were updated again to handle those new techniques. One strange one was a game program called Shuffle Puck Café which wasn’t that great a game, but was innovative for another reason. It had an interesting feature where it would let you make one legitimate backup copy. When you had it enable the copy though, it would read something off the original then would erase the original disk in the process first. I was able to modify their code though and created something I called Shuffle Copy. Basically you had to keep opening and closing the drive door to generate read errors for each track, so that it thought it had erased the original disk. Then you’d insert your copy and it would happily enable it and you had a working spare along with the working original. They released one other game I don’t recall the name of, but my copy program worked on that disk too. As time went by multiple techniques would be used together. I don’t recall which game it was but one worked sort of like what your video described. I had captured all the code out of memory and thought I had it fully cracked, but when other people tried to run it there were random failures at different times. What that turned out to be was that the software had saved a map of what hardware was in my computer. So when someone else tried to run it on a different computer the hardware wouldn’t necessarily match up, and it would trigger the random failures whenever it tested for that. Then there were more and more of the games like Track Attack that loaded additional levels off the disk at runtime, so it wasn’t just a single load anymore. That required capturing the code for the main program and also for each of those extra levels, and writing my own disk driver routines to load them at the proper times. It was a never-ending competition and a lot of fun. Anyway just one other thing regarding copy protection, one of the first copy protected games I ran across on the Macintosh they had actually made a pinhole through a track on the 3.5 inch diskette. If the program was able to read that track on the floppy with no error, then it knew it wasn’t the original. Other than that it was mostly just figuring out what opcodes I needed to patch to allow copied discs to work, searching for a pattern of bytes to find the spots to change on the disk, then modifying them with a disk editor program.

  • The annoying thing for me nowadays regarding floppy disk DRM is that I like to collect and play old games and install them from the disk but often this old DRM simply does not get recognised by my USB floppy drive or dosbox (I am not sure which is at fault here) so even with original disk's I can't get the games to work - so much for trying to be a good person and avoid resorting to "abandonware"

  • Dungeon Master was one of the most significant games of it era. The Atari ST version came out, then it was like a year later that the Amiga version came out. (No upgrade in graphics despite the Amiga's superior Graphics display and Blitter chip). When the Amiga version came out it had stereo sound and a few tweeks. This game was shockingly ahead of its time. Shortly after everyone cloned it, (Bizarrely not lawsuits), The 3 Eye of the Beholder Games came out, Lands of Lore and the Amiga game Black Crypt were all designed with the same user interface, (Actually it became the standard). Dungeon Master and its Sequel/Expansion, "Chaos Strikes Back" were two of my favorites games, (But there did seem to be some hard coding errors in the games..).

  • i dont think this is a good example of copy protection. think about it. all they did is make the player think the game is either bad or cannot be played, but the player does not know it is because its pirated. this means that if the player had any chance of buy the game, now they wont. spyro 3 is a better example, because it tells you the reason why the game does not work properly.

  • There are 80 cylinders (not 40) on a 3,5 inch Amiga or Atari floppy, and each cylinder has one track on both sides of the disk. There are 11 sectors making 22 blocks of 512 bytes on each track for Amiga (9 for Atari). This makes 880 kB disk size for Amiga and 720 kB for Atari. The atari disk format conforms fairly well to IBM PC format but the file system is not necessarily fully MS-DOS compliant. Most 3,5 inch drives allow up to 82 cylinders, some might allow one more, but it is not safe to assume that all do. While mountlists could be made on the Amiga to use specially built disk handlers and filesystems and tell it exaxctly how many cylinders, heads, and sectors a media would have, it was virtually impossible to build one that allowed the OS to directly access 82 tracks (902 kB) on one disk. There were combi disks made (published with magazines mostly) that combined the Atari and Amiga formats, requiring the lower side track 0 to have one sector, and track 40 at least, to be formatted for the Amiga. Often one side of the disk was formatted for Atari and the other for Amiga. X-Copy was fairly well able to duplicate any disk that conformed to a maximum 11 sectors, and even some of those that had no sector divisions, as long as a certain frequency was not exceeded. The chip that generated the disk write signal, had a limited output frequency, and tricks needed to be done to write HD disks for example. They required a drive where the motor speed could be adjusted.

  • I hadn't heard of this one. It's very sneaky. Two of my favourite "gotcha" anti-piracy systems were both from the 1990s. The first was the Turnpike email/usenet client that like much '90s software had a unique installation key for each copy. You could install it on as many machines as you liked, but any messages it sent were encoded with this key in the headers and if you received an email with the same key it would generate a cryptic-looking Windows dialog stating "Unknown message from myself." When people got this "error" message they would invariably turn to the product's own usenet support group asking why their friends couldn't email them, only to be told that their friends should buy their own copy. Brutal. It would probably have been described as a "self-own", had the term been around. The second was the official Scrabble game for the Psion PDA. Supplied on a solid-state disk, the game had an extra zero-byte file written into the SSD's flash memory that could be seen by, but not copied by, the file system. With this file in place the game played normally. With it missing, as happened when you cloned the SSD, the game would appear to play fine but every time you played a word all of the replacement tiles you got would be "E". After two or three moves you ended up with a rack of EEEEEEE and the game became unwinnable. I don't know if anyone ever reported this one as a "bug" but yes, I did discover it first hand when I bought a copy for my brother and tried to rip it off. I had a good laugh about it and went and bought my own copy. A success all round for whoever thought it up.

  • Either 1-2-3 or dBase used a different number of sectors on track 0 and once installed overwrote the track using a different number of sectors. That way if it failed to install the first time, or for any reason it had to be reinstalled, you were screwed. Then it was time to pay the manufacturer another $595 for a replacement disk that worked.

  • You forgot to mention that if the disk had dust, was ejected at the wrong time, or if there was a power failure during disk write, then the legally purchased copy could accidently be changed into a illegally duplicated copy rending it useless. Ask the devs how many broken disks were sent to them for new copies.

  • I had a C64 and (you'll remember this if you also had one) the floppy drives would get out of sync... basically they would stop working... sometimes a LOT. After fumbling around with repairs, eventually a disc was released that would repair the problem. It would force the drive back into sync and all would be well. I almost bought this solution but then I discovered the copy protection on one game was so unusual, that it would do the exact same thing as the repair disc. I truly wish I could remember the name of this game! I kept the disc LONG after I stopped playing the game just to fix my drives!

  • This kind of protection is good. It stalls pirates during the principle sales period, guaranteeing the developer fair revenue for their work. And it's tailored to the game so that you can't just crack one game that has it and then you've got the master key to them all. And it's noninvasive. It's self-contained on the original disk, doesn't do anything to mess with the computer running it, and doesn't need to get online. So it wastes pirates' time without making legitimate users collateral damage. Contrast this with DRM schemes that rely on rootkits or client programs or always-online checks (or some combination thereof) and which are often sloppily coded, while at the same time being jokes for pirates to bypass (meaning that people who bought legit copies get screwed while the pirates are laughing).

  • Best 'drm' I saw back in the '80s was on a game from IBM called Zyll (text based rpg, 8086 era). It was made to not work with 'diskcopy' by creating false checksums. If you tried to copy the disk it would give CRC errors. Files didn't exist since they hid the DOS format, by just leaving a few sectors. You booted to the disk, rather than booting to a DOS disk and changing to run a .exe. Eventually I figured out what they had done, but to no avail since I no longer had/have a 5.25" 360k floppy drive that works.

    • Ignoring the criminal intent, you can't encrypt the hard drive if it doesnt exist. Some old computers had the os as a read only chip (kinda like an nes cart) and the floppy disk was your only storage. You might have been able to get away with self wiping the illegally copied floppy, but would likely end up paying for replacing legitimate customers disks from false positives, which could get pricy.
