Alright, I realize the title might be a bit obscure, or sound slightly stupid (and I'm sorry if this has been covered before- I tried to find an answer for about 30 minutes) but here goes.
What I'm trying to do is have Mame quit a game and go back to the FE without having to press esc. Ideally, I'd like to have it mapped to something like "P1 START + P1 BUTTON 1". I tried to do this via the "Tab" menu, with less than great results. You can set multiple keys to a single command, I know, but not simultaneous presses. I tried to find a Mame .cfg file where all this info would be found, and thus changed, but I don't know where it could be. I'm running mameuifx32.
How did you guys set up Mame that you can quit a game using the standard CP buttons (and preferably without an encoder and shift function)?
Many thanks!
