These are full working cheats for USvsThem (memory locations of the old file were wrong for both cheats, maybe a memory map change in the latest mame releases).
Thanks updated, not able to check (big chd) but the existing cheating for "No hits sustained" pokes 2 addresses - but this one just pokes the one address. Is that one all that is required?
