This can't be fully finished yet... the following things don't make sense:
- Why PPU A8…A11 == b'0000'? That's the first sixteen patterns in the both pattern tables and the top eight rows of the top-left-most nametable.
- Why latch PPU A8 and A9 when PPU A8…A11 already == b'0000' ?
- Why latch PPU A12 and A13? They're rather difficult to control in a useful fashion.
