Already realized that games that use the emulator mame0139 as the "Street Fighter Alpha", player 2 does not work 2 buttons.
This only happens in the pc version. This in version 5.6, 5.7 and last tested
I've done everything, I tested generic joystick, original ps3, original ps4, whatever ... always one of the 2 players does not work 2 buttons A and L1 to be exact.
Putting those same controls on a raspberry pi 3 board, works perfectly
Please, any tips?
