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 ?
