sorry codec,... bad news. the pic you gave me, first in was not in the right size, i fixed it to 256*128
even after fixing that, i found out that the space required for this image would be around 13600 . that much isnt there in the rom.
if u look carefully at the celebi image too, youll see that the tiles of trees have been flipped, even the celebi is symetrical that is only one tile has been used and then flipped and used to save space.
well the story aint over yet, ill try expanding the rom and try/
