TODO: TODO:
- fix input port $06 and remove the patch, it doesn't seem directly connected; - remove the patch and understand what needs to be modified for the gfxs, game
- fix the background blitter/framebuffer, needs rewriting; doesn't crash anymore;
- inputs (some kind of ad-stick / pedal); - inputs (some kind of ad-stick / pedal);
