Here's the code. The background is completely messed up as it uses the tiles but sometimes they flipped and in the wrong places.
There is no problem with the data, just the code.
edit: I think that the gba is reading it as a text background hence why it thinks it is 512x256 instead of 256x256 and some of the tiles are flipped. Problem is I dont know how to fix it!!
