Notes:

TODO:

- Real machine has ROMs for protection, but I don't know how to access the ROM,
  so I'm doing something that works but is probably wrong.
  The interesting thing about that ROM is that it comes from other, older games,
  so it isn't needed, it's just verified for protection.

- Some games display "GFXROM BANK OVER!!" or "GFXROM ADDRESS OVER!!"
  in Debug build.

- Screen flipping is not perfect.
