Reply To: LR-MAME. How to set custom controls?

[helpman]

I already visited that wiki, but how can I know what button uses lrmame for what?
a, b, x, y, start, select, l, l2,l3,r,r1,r2,r3…
if I just want to set buttons 1 to 7, 1p, 2p and coin?
is 1p start and select coins?
a, b, x, y, l, r will be the 6 first ones, what’s 7th? l2?
how do I set a different keymap for a rom? (i. e. 6 games buttons wont use button 1)
