I want to convert the Japanese music to the US Rainbow Islands.
I used nes2nsf to get a handle of the music location in ROM:
US - 1C010-1FEB0
Jap - 1C010-1FD00
I then copied the Japanese bank onto the US one.
The game won't boot now. Can someone check what I've done wrong?
download:
contains hack and original US game

Also, is the FCEUX tile id the letter code in hex? like 0A are all A's in the game?
