Questions regarding patches/cheats, snowblind engine

[Carsomyr]

I was just curious now that we have the ability to play snowblind engine games in hardware mode, is it possible and what would it take to develop some sort of patch to make them manage memory better? I'm also curious how patching/cheating works in general, I have coding experience but not with this sort of thing Any theoretical responses to the snowblind thing welcomed, and any suggestions/links/etc to maybe getting me started on doing my own patches would be greatly appreciated
