you can find a lot of interesting things and ideas for sure.
but i don't think these codes are similar to ps3 gamegenie.
the bit writing structure is somehow similar to codeunique as aldo has said, but the methods are mostly based on search and replace and not static offsets. the problem is, they have to choose advanced techniques as the savefiles could be changed with every saving, and so the value offsets. only on a fresh savestate the offsets are equal on every save. i think the checksum handling is done by the app itself and not by codes, but there i am also not sure about.
these 6 codetypes use a kind of bitmask searching i think, with adding different offset values. but i have to say these are very difficult to recognize or even to follow in savefile.
and about the 4 multi write codetypes, these should be easy to convert (still assuming), but i haven't looked at them. i only think about the old ps2 action replay codes which were "compressed" into single lines to avoid hundreds of codes, which could freeze the game.
though it would be nice if some hacking experts would share their knowledge, but i don't think this will happen anymore.
i will try my best, to find workarounds to these unknown codes, but it will definitely not work for all the codes, which also should not be the goal. and to be honest, it is great aldo has come this far with BSD and cheatcode support and i am more than happy with this result.
reading about the different codetypes from geckocodes, some things are similar about the explanations, but the codetypes are different. too bad i am no hacker expert or alike and the definitions are quite confusing to me.
