Re: Poor keyboard

Re: Cart for Homebrews...

Re: WIP: Reversi

I have programmed games for MSX and never had these kind of problems, even on real hardware. Will try to port the gyruss stars and see what happens. Going to Gothenburg tomorrow though, for a retro gaming weekend. See you there, Carlsson!
