I've set up a tablet version of mame, (0.139u1 to be exact) and I bought a mad catz C.T.R.L. controller for it. I went into settings to configure it, and everything went smooth except for a major problem with the mame a and b buttons. When I try to set my controller for the a button to be x, the system accepts it, but the button doesn't do anything in any game I've tried. Even stranger, when I configure the b button to be y on my controller, it's causing it to be both the mame a and b buttons together... The reason I know this is because that's how you roll in king of fighters games, and that's what the button does. Also causes you to both jump and shoot at the same time in metal slug games. I've also tried configuring mame buttons to other controller buttons like L1 and R1, and even the dpad, still no luck. Any help with this would be great, as I play mostly fighting games and the a and b buttons are mandatory for some combos and special moves, and impossible to pull off without them. Please help!
