Can anyone help me with this? i am translating Body Harvest on N64 to Brazilian Portuguese, but when i try to fix the checksum of the rom, i can't because the chksum64 doesn't work, it says my system isn't compatible and i must have a 32 bit system. this and other 32-bit programs says the same thing. anyone knows some program for checksum nintendo 64 roms that works on windows 7 - 64 bit? or i really need a 32-bit windows to run these kind of tools?
