My quesion is how hard would it be to remaster the graphics for some classic games?
Incredibly hard. You'd have to reverse engineer the code and write gazillion patches. All in 68k assembler. Oh, and someone would need to create the new artwork, too.
People are always brainstorming ways to have new games for the Amiga so maybe this method of remastering would be a good start?
No way. It's far easier to write new code.
Maybe Natami would be a good platform to aim for?
Err, why?
