Just downloaded Launchbox 13.1 beta 4, paid for BigBox, imported mame romset .251 merged, and most games start. This is a cabinet with 4 joysticks.
Questions
1) Should all mame games use mame .251 emulator (default) or RetroArch? If they should RetroArch how do you get all Mame games to default using this emulator?
2) How do you configure the 4 joysticks and buttons on cabinet for all the mame games? None of the buttons are mapped or working.
