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.

  • Too bad it turns their boards into time bombs that need sensitive bits replaced later on. You can play real "rainbow" edition standups at the pinball and comic show in Tacoma most years.

  • i also have a suicide board, but a natural one. it is a Galaga dual pcb board - probably an original board that sometimes comes up with ram faults and even if i change the particular ram the same ram fault will come up sometimes. i have it now for almost 20 years and i have to repair it at some point. should be no real problem. with my picoscope i should check the signal integrity of the involved chips and noise on the +5V rails. maybe they are too noisy because of dead caps. i also have circuit charly, gyruss and kung fu master. i love them!

  • The copyprotection was important during the board's service life (although hoo boy was it exploitative of the arcade operators). But with the board discontinued so you couldn't have Capcom reflash it for you even if you wanted, it's good that people have formed a workaround.

  • This is exactly how Street Fighter 2 Turbo was invented. It was a hacked version of Street Fighter 2 Championship Edition. The hackers and arcade community called it Street Fighter 2 Rainbow Edition. Capcom took it and toned it way down giving us the turbo feature and new movesets. You got the date wrong for the Neo Geo AES. It was released on January 31, 1990.

  • Although somewhat effective, I find this type of suicidal DRM dangerous, for the environment, it is not feasible to destroy functioning electronics for the sake of protection, all of these boards (and batteries) have to go somewhere.

  • Oh wow! This is such good news about reviving CPS2 boards. I bought a bunch of them back in the day for my Candy Cabinet and then life moved on. SO I just stored them away. I'm not sure if they actually work now. But it is good to know that if they are dead, that they can be revived.

  • I spent some time in Panama City Panama in the mid early/mid 80's and they had entire arcades full of machines that were bootlegs. They weren't selling boards to legit arcades but using entire cabinets that weren't even meant to look like the original. A lot of people would play the bootleg machines in those places because you got two credits per quarter instead of one.

  • You always need a two way key. On your side it makes no sense, the key makes no sense, but the combination provides blind data to a cabinet. Keeping data from being intercepted means you add hardware data to the challenge matrix. Then someone will have to virtually have your machine. But in the long run, your just selling a flavor in a starch with chunks of matter stired by a guy in a shmock were great vats of the, "drug", can't be accessed. Particularly cartoon manga.

  • 1:52 Lots of guesses were cut? This must have something to do with the cheaper hardware having an inferior random number generator. Because they used cheaper sound chips, and the best random number generator came from the white noise generator on the sound chip. Next thing you know that chicken on Chun Li's stage isn't flapping anymore and Dhalsim starts twerking instead of doing his little YMCA dance. These are the small joys which draw us to Capcom games! It's certainly not the gameplay! That's when I find the manager and say listen, sir, I know exactly what's going on here. And I don't even care about the quarter. I'm going to make this real simple for you. Either you're calling Japan and apologizing or I'm calling the police. If I wanted to play on a MAME box I'd be at the maker fair with the real nerds. Just because I'm drunk at a barcade doesn't mean I'm stupid!

  • Damn so if Capcom had not tried to compete with the SNK home system. The CPS2 would never have been defeated, on the bright side, it also means that they can revive dead boards which would save others from meeting the dump when all they needed was a new battery and to have the game re-installed on the ROM.

  • This explains why most arcades in the 90s practically have the same games, as they are all actually bootlegged CPS1 games. Only "premium" arcades have newer games, Those cheap ass arcades still survives today in some places.

  • It's honestly super cool, but it is important now more than ever to preserve arcade history. Ive been buying emulators, cabinets, coin doors and joysticks. Its something i grew up with and I think everyone should experience this part of gaming history. In a way i think all these games are good places to start on your way to becoming a gamer. I want my kid to get frustrated like i did playing mortal kombat 1 and 2 and seeing the sheer difference of what an easy and a very difficult game is. I want them to play my ps1. I want them to grow up a little like i did. Except I'll be there this time. Showing their ass who was there

  • can't decide if capcom is good at drm or no. on one hand, there's this and on the other there's capcom.sys capcom.sys being a drm driver that capcom made and that ended up being such a horribly coded driver that it became the most popular method for unsigned kernel mode code execution on windows (eg. malware drivers like rootkits)

  • Some bootleg boards were superior .. ie: originals often had custom parts where the copyboard would use more generic off the shelf parts -- ie: were more repairable. Likewise, stuff like Nintendo boards used 'reverse' monitors which was unusual.. the bootlegs worked on any normal arcade monitor. Many bootlegs were lower quality, but many were very very handy.

  • Anyone who blames MVG for "selling out" to Raid Shadow Legends is a weiner. But it's okay. There's this wonderful invention called *'SponsorBlock'.* It's great. I'm going to talk about it, and they don't even sponsor me, so I'm not "selling out". sponsor.ajay.app/ It relies on people submitting videos to the database with timestamps for when the ad begins and when it ends, and it handles the skip automatically. It supports Firefox, Chrome, Opera, and something called "invidio.us" (which I'm told is an alternative SEworld player, or something). Get it, and stop being pussies. It's easier than pressing right on the keyboard arrow keys, like, five times, I guess. Get it, and move on with your goddamn lives.

    • Yes, we know that Raid Shadow Legends is bad and the sponsorship videos are spreading across SEworld like some weird and irritating rash. But complaining about it isn't going to make it go away. Instead, you can minimize how much it's going to affect your viewing pleasure and let RSL know you think they suck like an adult - by complaining to them on Twitter, or something. Complaining to the people on the bottom rung isn't going to do a whole lot more than denigrate the people who would otherwise be making content for free. And that's not cool.

  • Were/are the batteries on these boards recharged when ever the system is connected to external mains power. I would've thought so. Also, couldn't the data in the battery backed RAM be saved to an image using an IC reader/programmer, the original RAM chip replaced with a flash EEPROM and the same image written back to it.
