How Capcom's clever CPS2 Arcade Game Copy Protection stopped bootleg games | MVG

  • Arcade Game bootlegging was rampant in 80s and 90s with many arcade manufacturers including Capcom in the firing line with their CPS1 arcade hardware. But Capcom learned from their mistakes and the CPS2 hardware from 1993 to 2007 - long past its end of life - became impossible to crack.
    This is the story of how Capcom kept bootleggers away from the CPS2 arcade hardware for over 15 years and how different individuals eventually lead to the ultimate defeat of the encryption.

    Oh damn, is this about the Suicide Boards? I hope you follow this up with the decryption of the CPS3. That took forever to get done & we've only had real CPS3 emulation for a relatively short time in comparison.

      The CPS3 was generally accepted as the best way to prevent anti encryption but there were several boards and chips (including the 45djp) the Sprite count caused this to expose certain exploits. The battery can be primed meaning no data is lost, being stored on the board.

    I’m one of the 4 people who donated the Japanese version of Street Fighter Zero 2 Alpha to Razoola back in 2001 (My name is Johnick on the CPS2 Shock donators page). The game was almost 6 years old at the time which is about how long the batteries lasted in the board. If we didn’t donate it to Raz to dump and create the XOR tables back then it probably wouldn’t have been playable in emulators until 2016. Great vid, I have fond memories of the CPS2 days, Raz deliberately released the XOR tables for the oldest games first and staggered the releases so as not to hurt Capcoms sales, as they were still making CPS2 games at that time.

    One question I have from watching the video: during your research for this, were you able to find out if Capcom disclosed the suicide board “feature” to buyers when purchasing the boards?
    Preventing piracy is fine, of course, and I think that was Capcom’s principal concern. However, I think I would be rather unhappy if I were an arcade owner paying for a board repair every few years not knowing that what I was really paying for was essentially a license renewal for *hardware* I had legitimately paid for.
    Capcom seems to have pulled off something really special here - they created a protection method that was not only very effective at preventing piracy for a relatively long period of time but also created an additional revenue stream. Like many anti piracy schemes legitimate customers get punished in the long run :(

    • @Finfection
      @Finfection Před 5 lety +27

      I don't believe it took long for arcade owners to possibly figure out how to replace the battery themselves. You only had to replace the battery every 3 years or so. And once you removed the old battery you had one hour to solder the new battery to the board. Outside of having the new battery be a dud, this was very difficult to mess up. Now the suicide battery on CPS3 hardware was a different story as it was much more difficult to replace the battery on those without killing your board.

      I hate DRM on principle for much the same reason.
      I get why it was done, but it just makes game preservation in the long term so much harder.
      And while some argue that the companies/people that makes these things 'own' them and can thus do anything they like with them...
      I disagree that this is a valid perspective, and certainly there's a reason Copyright was originally tied so intimately to the idea of the public domain.
      Really, the propaganda campaign over many decades that has created this idea of 'intellectual property' by false equivalence to ownership of physical items (ignoring all the secondary implications that 'owning' something intangible like an idea, concept, story or whatever brings) is a highly toxic one, but it doesn't seem that anyone in power actually has any incentive to fight this battle...
      So the rest of us have to muddle through and deal with legal grey areas (or outright illegal actions) just to keep these games from dying out completely...

    Really though, companies like Capcom after so many years should have been the ones to offer an official permanent ‘fix’.
    I can understand why they did this at the time, but by the mid 2000s that RAM should have been replaced by ROM officially.

I am in the process of a full recap of the Zennith/K7000A Wells Gardner chassis monitor combo and also recapping the power supply. I will be restoring the wood and repainting it as well.

      It's not a bug, it's a feature. Capcom made arcade owners rent games they bought. It guaranteed a steady source of revenue from games that arcade owners already paid a lot of money for. Capcom could advertise new games when owners sent their old ones in for repair. Capcom could even refuse to service existing games and force arcade owners to buy new ones.

    • @figment1988
      @figment1988 Před 5 lety +8

      for the most part, while most bootlegs had some interesting perks, many players hated them due to the fact that they killed the balance in the game (which was very true for bootlegs of Street Fighter II' Champion Edition which were notorious for its features such as changing characters during a fight, and the often one sided ability to make a hadouken wall with Ryu and Ken's Shouryuken while repeatedly spamming the quick punch Hadouken made it possible to stack hadoukens one after another to create a ''Hadouken Train'') and this led to many companies to send cease and desist orders to those bootleggers, and in Capcom's case, it led to Capcom USA's James Goddard (who would later be known for creating Dee Jay who was the first Street Fighter character made by Capcom USA) to create the official upgrade which is Street Fighter II' Hyper Fighting as it's known internationally or SF2' Turbo as it's known in Japan

      @TrimeshSZ Před 5 lety +1

      Yeah, but it does make it clear that it's not ROT13, a simple XOR or some other bogus crypto. In fact, it's implemented as a pair of cascaded 4-round Feistal networks which are both 4-round and use 6->2 S-boxes (different for each round and different between the two networks) and have different key scheduling. The first network takes the key and the low-order 16 bits of the address, then expands the result to 64 bits where it's XORed with the (same) key and used to key the 2nd Feistal network that takes the opcode data read from the ROM and produces the decrypted opcode fed to the CPU.

      @@Xx_m1k3_0X1onG_xX The CPS2 does not have more RAM than the CPS1. Both contain 64 Kilobytes of Work RAM. The big difference is the ability to access far more ROM for storing graphics and sound data. This allows for much more animation, larger sprites, more sprite graphics overall. The Street Fighter Zero port to CPS1 has smaller graphics ROMs than the CPS2 original because the CPS1 didn't support graphics ROMs that large. The port of Street Fighter Zero as well as the CPS1 version of Rockman The Power Battle max out the CPS1's memory capacity I believe. They each have 8 Megabytes of graphics data, which is only 1/4th of what the CPS2 supports, 32 Megabytes.

      Yeah, and I think some bootlegs were even designed to transform arcade cabinets into gambling machines. I remember about that from an journalistic investigation on how some French criminal organizations had such bootleg arcade machines in cafes and French pub (the famous "bistros"). In apparence, the arcade game was an regular JAMMA arcade game. But you had to do a sort of "Konami Code" to access to a hidden menu and voila you were having a gambling machine. Of course it was illegal (because everything around gambling is regulated by the Francaise des Jeux with associated taxes to them).
