iMame4All Coin 2, 3, and 4 button

[guitarmandp]

In the Simpsons arcade game if I want to play as Maggie, Bart, or Homer I have to respectively put the coin in eacher coin 2, 3, or 4.

On iMame4All is there an option where I can be coin 2, 3, or 4? On my PC I just hit the number 6, 7, or 8? I tried remapping and that was a nightmare. Is there any easy way?
