There was some recent news around game sites yesterday regarding the decryption of a Capcom arcade system board named CPS-3 or Capcom Play System 3, the sucessor to CPS-2 which the Street Fighter II series and alot of Capcom games are based on. So what's the big deal with CPS-3 being decrypted you say? Well, as you may (or not) know, in the emulation world, decrypting the protection on arcade boards is a major step in the right direction to begin emulating these arcade games, which is another story on to itself. The noble reason to emulate these arcade games is to preserve them before they go out of existence, some games are already lost for good. CPS-3 had only six games made for it. The first being an unreleased game called Warzard/Redearth, then JoJos Venture and finally the Street Fighter III series. The CPS-3 boards were short lived because of the high cost and the fragile nature of the protection scheme resulting in dead boards. While some my not care, be rest assured that there is a group of technical wizards out there preserving arcade systems from the 1970's till today and that gives me a warm and fuzzy feeling.
