Can’t seem to get this to work. There’s no core input options in the retroarch menu so I can’t save a remap file. If I change any buttons in the mame “TAB” menu they don’t save when I relaunch the game. If I edit the button configs in the config file located at /opt/retropie/configs/mame-libretro/retroarch.cfg the changes don’t seem to load when I launch a game.
Has anyone got this working?
