when I try to replace the nsmbds's jyotyu tileset by newer smbds's tileset its just corrupted and doesn't works, I tried to replace every recommended files but still doesn't works... HELP PLS!!!

iirc newer ds uses a code hack so that the jyotyu tileset uses different graphics depending on if its supposed to be the underground/lava/snowy/etc variant instead of just a palette swap, so it wont work unless you apply the proper code hack to your rom

if I try to replace my hack by the nsmbu for nds's jyotyu tilesets its like corrupted
can you explain how is that possible pls ?
