What to do with 6 bit GG NES codes is another problem.they are an invention of the devil and I'm not sure that supporting them at all is a good idea when it's not possible to determine if the nes_slot:cart:prg_rom.mb address = PC in any meaningful way.īecause of the amount of paging the NES does they are frowned upon by the cheat community for causing bugs/crashes. Is it possible to change the way it works so that it looks for a match using the 32K block size first (58ef,d8ef,158ef,1d8ef etc) and then falls back to a 8K block size (18ef, 38ef, 58ef, 78ef etc) if it can't find a compare value match on the 32k block size. From what I've seen in NES gg codes most codes use a 32K block size. However, because of mirroring cheat_a is poking 18EF & 01C2 as they match the compare value.

I appreciate my fix is a hack as I've taken ram=maincpu which is strictly wrong, but it does make it write to cheat.simple and it does work when read back in. This method of sound output will only work when used with external device/emulator. json file if it's a softwarelist image loaded, I've found a few lynx SL cheats before the modification above and they saved to cheat.simple file fine, but there are no lynx*.json files at all in my cheat folder. Without the hack/modification it doesn't write anything at all be it json, xml or simple (written = false and the Unable to write file message pops up).Īlso (partially related) it doesn't write a. Is this for the simple format as the xml format can't work with ram device cheats? The json cheat format should always be written because it supports everything.
