Hmm, I see that there is a “Coin A” shortcut if you use the shift function with button 1, maybe that means that player 1 get a coin with player 1 button 1 and player 2 get a coin with player 2 button 1? But I don’t know really, sorry, I think someone else have to advice you on this.
There is some info that you can make your own shortcuts and macros on the IPAC website though, no idea exactly how but it seems like you can do pretty much anything with it if you invest some time in it.
