1/***************************************************************************
2
3  Italian bootleg of Head On, by EFG Sanremo (late 70s to early 80s).
4  The game title is unknown. Someone wrote FOOL RACE on a piece of tape
5  on the pcb, but that's not really credible.
6
7  It's on much cheaper hardware than the original: 8080 instead of Z80,
8  and less RAM needed with the gfx tiles being on ROM.
9 
10TODO:
11  - Sound is unknown, probably simple and discrete
12  - wrong coin handling, it writes to port $01 to reset coin status?
13  - other unknown writes
14  - dipswitch settings
