Joystick not working in Mame-libretro

[krupper]

I'm able to use my PS3 controll with no issues on Raspberry PI3 and latest Retropie build . I have built a new 2 player with 6 buttons control pad using Ipac 2 , I'm able to navigate through the Retropie menus with no issue joystick works fine. However when I go to play a game the joystick doesn't respond (Mame-libretro) the buttons do work. Also if I select 2 player game everything works fine for player 2 the buttons work on player 1 but not the joystick. I have tried remapping the controller and nothing seems to help.

Please let me know what I should try next.

Thanks, Krupper

@krupper is your controller maped as a joystick (-> axis) or as dpad (-> buttons)?
If your joystick is maped to axis than you might want to add these lines to the input config of mame:

input_player1_analog_dpad_mode = 1
input_player2_analog_dpad_mode = 1
input_player3_analog_dpad_mode = 1
input_player4_analog_dpad_mode = 1

This maps the joystick axis of the (left) joystick to the dpad of player 1..
If you have 2 joysticks and want to map each one for a seperate player use the value 2 for player 2... if you only have 2 players remove player3 and player4
Play around with that (if your joysticks are mapped as joysticks!)
