One other minor thing (ok, maybe not THAT minor) I have issues with, is that I can't seem to get the 49ways to navigate the roms in mala. They work fine ingame, but I can't seem to get mala to see them.
I check the checkbox under contollers to enable joysticks, but after I exit the config and go back in, it's unchecked again, no clue why.. Windows sees them, mame sees them, but not MALA, strange..
