is8BPP in sub_8199D3C is actually isAffine
luckytyphlosion opened this issue · comments
Affine tilemaps are 8 bit, while 4bpp and 8bpp are 16bit. In the function, we see that if is8BPP
is true, then the game does an 8 bit copy, otherwise it does a 16bit copy. Thus, it makes sense that is8BPP
is actually isAffine
.
