Gauntlet, TMNT (though this has a 2-player version, as do X-Men, Simpsons, etc), and Rampage have been named. I believe some of the D&D games require separate coins as well.

Sorry
Just checked
Rampage (Rev 3) doesnt even need player one player 2 buttons lol
TMNT 4 player does
TMNT 2 player doesnt
dd1 doesnt
dd2 doesnt
dd3 doesnt
Final Fight Doesnt
The Simpsons 2 player Doesnt
The Simpsons 4 player Does

So it seems all 4 player games need a coin two but there is a 2 player alternative version for most games which can be played perfectly with only one coin button

I agree with ghettodish's suggestion. Wire both your coin1 button and coin1 slot together. Do the same for coin2. This way you only need 2 inputs on the I-Pac instead of 4.

I use this setup on my cab. When playing a game, you have the choice to either put in a token or press the coin button to add a credit for a player.

To clarify, don't wire ALL of the buttons and slots together. Just the button and slot for each individual player. You should only need the Player 1 and 2 coin inputs on the I-Pac doing this.

I don't think the inputs on the IPac are the issue -- the issue is running an extra wire from inside the CP to the coin door.

let player#2 toss in a coin.
keep it real

Thanks for all the suggestions!  FYI, I wired up the coin door last night and decided to combine some of the suggestions to reach an acceptable compromise.  On the panel I have coin 1 mapped to 5 and coin 2 mapped to 6.  In mame I have coin 1 set to 5 OR %, and coin 2 set to 6 OR %.  Then, I wired the coin slots on the coin door together and mapped them to %.  The end effect is that I have two independent coin buttons on the panel, and a coin door that will give both player 1 and player 2 a credit when either coin slot is used.  This accomplished my goal of not having to drill another hole into the back of my CP (I only had one wire to work with outside of the CP, that's why I had to wire the coin door slots together.)

I'll just have to make sure that people don't use the coin door for the few games where it matters.
