TODO:
Find 'payout on' command to add simulator
Tomasz Slanina 20050225
- colors (4bpp tiles and 3bpp palette ? something is wrong then ....)
- 8255x2
- ball sprite (maybe it's something else in real machine , not sprite)
(hardcoded tile number and palette for now .. maybe x/y must be swapped)
are writes to 8000/c000 related to sprite tile/pal ?
