Tank Force US 4 players version

This romfile comes from a standard Namco System1 pcb.
Note:This was a failed conversion attempt,since inputs on jamma connector don't work (only coin,mapped as follows: Player 1 coin 1 -> coin 1,player 2 coin 2 -> coin 2,player 3 coin 3 -> start 1,player 4 coin 4 -> start 2) so in game setting mode you can't change anything and then you can't play.The system is ok (tested by burning the 2 players version),so the original design for this game version uses extra hardware for 4 players input management.
The eprom is a NEC 27C1000
The rest of eproms are identical to existing set
