+Notes:

+ 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...
