Todd, my Phoenix is in great condition except for the button someone installed in the front in the coin door. Trying to decide whether to leave it or not.
Been looking for a smallish rom hacking job. Maybe I'll do this one.
Only thing that bugs me about using a jumper on player 2 start to insert coin or CoinUp is that if a player hits any button that inserts a coin during gameplay, you end up stuck on a static screen for an indefinite amount of time. I'd rather just have the ROM not really care about the coins anymore and always be in attract mode until someone hits start.
(Yes, I realize that in practice, an occasional static screen isn't going to cause problems. . . I'm just being anal. )
