I am seeing images just need to correct that offset and off you go
ObjH1234 or objV1324
you may need to change the tile size to view right but alot is there just weind looking.
Gba8bpp may not work for all the images.
And this game has slight compression...so that migh be the problem too. that pac foldr uh jeez...
Time to get yourself an emulator that lets you view the graphics in a seperate window get the size and other aspects form the emulator and possibly a crap load of screenshots.
