always facinated by these.

some ideas: - could try to add another player. just need to map 4 more keys. IO should be fine doing it the same way (dont think itd need thread or whatever) the io is super fast in the qemu scenario.

- rather than have this in the MBR. make an MBR where you can select this sector to load as next sector and jump, maybe even with ability to return. *you can then expose other games too if ud ever be bothered for snake or minesweeper :D

just some tinkering ideas. cool project and hats off. its always more tricky than it looks these things!
