===== BAT Collision =====
HuC's ''map_get_tile()'' function seems broken, but you can use ''vram[]'' instead.

e.g., ''tile = vram[y * BAT_width + x] & 0x0FFF;'' 

The above code would get the tile at ''x,y'' (8x8 tile coordinates). ''BAT_width'' is the width of the virtual screen (32, 64, 128). The ''& 0x0FFF'' part strips out the palette data so you are left with just the tile number.
