I'm trying to configure my SNES-style iBuffalo controller to work in ADVMAME and I have to admit I'm getting nowhere. I can bring up the menu (TAB button on a keyboard) but the labels are somewhat esoteric to me. I don't suppose anyone has a mapping that would clarify things like D-pad up/down or fire button? Or an .rc file that works for an SNES style controller? Thanks for any help!
