yeah, friendly or not? cause i'm seriously doubting that it's possible to rom hack with Windows 7. everytime i run a compression program with LZ77, the program freezes. whenever i run a Tile Editor, i get only the top line, and it's usually random pixels that look like a 3 year old finger painting. again though, only the top line >_< haven't really had any problems with the hex editors though, they seem to work no problem. it's mostly the LZ77 that's the major problem. can't do anything to a game without it.
