Expand #7997 (save states files naming) to cheat files

I know this came at a really bad time, right after release. To be honest I didn't expect it to be today.
But without this #7997 looks like only half done and is a missed opportunity.

Yes, good point. The whole "game id" logic needs cleaning up.

There's always 1.2, and I'm hoping to release that a bit faster...

Heh, famous last words.

Are there any other things which use the game id? There's the "fixes" and I think the savedata manageement (but the latter is a mostly lost cause with homebrew), and the title and UI.

We should probably have the logic in GenerateSaveSlotFilename moved to the gameinfo cache, and have that be one of the things it's responsible for - resolving the game id? Then we just need "current gameinfo" somehow?

Yes, exactly my plan :)
