Gameshark inside

People, did anyone try to reverse the CD version of Gameshark? Or maybe someone has the source code? I'd like to understand how the cheat code system is implemented in it. I tried to reverse it, but because of not very good ownership of the assembler, I could not do it.

Action Replay V3 and V2 source. Not the full source though as it's missing some crucial stuff in regards to the low-level hooks and kernel handlers so it's pretty much useless. As for how the cheats work though, it might be useful :)

Yes, I saw how cheat codes are implemented. Not at all like in my implementation. In any case, very useful information for study, thank you very much.
