Hi! I use MAME4droid (0.139u1) with the matching rom set. In the settings/input/external controller/automap options I have the ?Thumbs as coin, start and L2, R2 disabled? ticked.
Ingame, OPTIONS/SETTINGS/INPUT/EXTERNAL CONTROLLER/DEFINE KEYS/PLAYER 1 is disabled by the automap option. (so it?s global and I don?t have any individual settings per game)
I turned of Coin, Start and Settings on my display so that it?s nice and clean. I can drop a coin by pressing L3 and Start by hitting R3.
In your case try Mode/Controller autodetection and Automap options/L1,R1 as Coon, Start and L2, R2 as L1, R1.
In Input there is a tick Box ?P4,P3,P2 as P1? this is unticked on my device.
I hope that helps, if not let?s try something else to find a solution.
