CwCheat Support

[LunaMoo]

@Xaymar currently all cw cheat code types are implemented except 0xB which was likely never used by anyone anyway. You can see them all under this switch.

When cheats doesn't work in latest version, it usually means one of the three things:
- address differs on ppsspp vs psp - very common, most of the "help me cheats doesn't work" posts are affected by it and nothing much we can do about it:|, althrough sometimes using "psp-1000" in system settings might help,
- cheats are not using cw cheat format, but something which only looks similar like nitePR - saw people trying to use those at least few times,
- cheats are broken in some way - fair amount of psp cheats does not work as expected, work only in certain areas of the game or in case of typos/improper format even only with certain plugins which might have better bad code detection than ppsspp cheat engine which only corrects most common user mistakes.

I doubt we have any errors left in latest ppsspp cheat engine code at least not in commonly used code types, but recently it got some attention, so few things were added, broken and fixed again after 1.0 was released, so the guide from first post to get the latest build when using cheats still applies here.:]
