OAM (low) table - handles all sprite tiles that are on screen. Each OAM slot contains 4 bytes of data: [XXXXXXXX YYYYYYYY TTTTTTTT yxppccct]
XXXXXXXX and YYYYYYYY bits are the on-screen coordinates from the top-left corner, TTTTTTTT is the tile number, and yxppccct is the tile properties. Each OAM slot are ordered from high priority (in front of other sprite tiles) to low priority.
Ranges from $7E0200-$7E03FF, therefore there are 128 OAM slots.
