@SilverDeth The only emulator I have used that it doesn't crash in is ines, so I have some 32-bit ines binary in ~/bin. I figure that I could fix it with a hex editor and a memory map of the NES ("Unrecognized instruction: $1B at PC=$98C6", and I don't know where in the NES's RAM that address would appear at, ines treats it as a nop) but I haven't attempted yet, so if you don't find a better version, it wouldn't be hard to replace it and make one.
