is "Insert Coin 2" necessary?
currygoat11:
In designing my system, I have not accounted for "Insert Coin 2". I possibly made a wrong assumption that it wasn't needed. I could utilize a shift function of the I-PAC to get it to work if I really need to..... but I dunno if I need it (?)
I appreciate your comments on this subject, thanks!

There are some games that will require the second coin button to insert coins for player 2...but there are ways areound it, you could change the control file so they are the same button...or wire the single button to both inputs...but with those you always add both coins.
Jakobud:
Yeah you might need it for some 2 player games. For example, in TMNT, it's a 4 player game. But I'm pretty sure you can't insert coins only in the first slot and give credits to each player. Each player has his own coin slots dedicated to them. They have to insert coins in their own slots to give themselves credits.
An alternative idea is that you could have one master coin button, and in Mame, assign that button to all the coin buttons, so everytime you press it, it gives credits to everyone.

Thanks for the info!

Yeah, as others have said, you can use shift. But that will confuse guests.
As mentioned above, I just wired a single "credit" button to both the Player 1 Coin and Player 2 Coin inputs.
