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

[helpman]

I already remapped it for neogeo, but it’s easy as it only uses a, b, x, y start and select as coins.

what I’m trying to guess is what are the next buttons to map them to my 5-7 buttons. l, r, l2 maybe?

for custom keymaps per rom, there’s an option on the M menu before the game starts right?
maybe I can create a custom remap file for 6 button games and load them as needed using that option
