Dear all, after a few months of testing we are extremely happy to release the new clean desuicide / security programing method for Capcom's CPS2 hardware.





This guide is the result of almost two years of work by an small group of arcade enthusiasts to unravel the secrets of the security implementation found in one of the largest and most popular arcade platform systems. Thanks for this work it is now possible to fully preserve any CPS2 systems as original hardware.





Over the coming weeks additional details about the CPS2 hardware internals will be released providing unseen insights into how Capcom implemented security.





Thanks to everyone who has helped test and validate this release throughout the summer, special thanks to Bill DeLeo,

Jeremy Walski, Leonard Oliveira and rtw.
