OK here is what I did, to make it work, use dos box + dfend reloaded, to be able to use snes tool with windows 7 64bits, add a header, use the 60Hz patch, delete the header, tried every patch, the Spain game only works with the PAL German patch! after that fixed the ROM info with IpsAndSum.
If you just want to play the game at 50Hz, just apply the pal German patch.
no matter what i tried, the 8x16 patch doesn't work, so bad luck for Spain users!
all the steps works, the same for the french game, also what's the .asm file for?
Anyway thanks for your work, the soundtrack is amazing!
