Notes:
      Z80 @ 3.6864MHz [22.1184/6]
      AY-3-8910 @ 1.8432MHz [22.1184/12]


Emulation Notes:
 Corrupt Tile on the first R in Carrera? (unlikely to be a bug, HW is very simple..)
 There is also a 'Bomberman' title in the GFX roms, unused from what I can see.

TODO:
- Are colors 100% correct? Needs a reference to be sure.
- There are reel gfxs on the roms (near the end), left-over or there's a way to enable it?
  Update: if you trigger a normal irq 0 instead of a NMI the game will change into a proper 8 liner game without inputs. Investigate on it...
