A recent announcement by the Arcade Hacker Project has presented some amazing news. The group has successfully reverse-engineered the security protocol on CPS2 boards. To us mere mortal Arcade Punks this may seem inconsequential, this means that boards that were already dead can be resurrected through a software process, which implies far less risk in regards to destroying the board, basically if its broke, this shit can be fixed!
Its a known fact that the CPS2 hardware was iffy at best, the battery and security chip on CPS2 game boards could fail without warning, rendering the entire board inoperable. With no support from Capcom in repairing archaic boards that they no longer have the means or the financial need to repair–doubly so with the addition of CPS2 games on the NESICA arcade distribution method–hobbyists and arcade enthusiasts had to rely on a risky hardware-based method of resurrecting these boards, which could still result in the board never being operable again if incorrectly performed.
While details are currently not available on the how, they are preparing to not only release the details, but make their findings open source and free so that anyone can use their code to resurrect any dead CPS2 board they might have.
