Retropie 3.5 and Picade console

Dear all,

I just got a picade console and though I could make it run with a rasp pi2 and retropie.

I got everything built up and installed in just few steps but I’m now facing a controller issue.

At first boot the picade console (joystick + buttons) is not automatically detected. After holding a button it s seen as a keyboard and the keys mapping setup works fine.
Once in emulstation I can use it to navigate through the interface without any issue. Playing Doom works fine too.

I then try to copy som n64 roms and play with. Unfortunatelly in the game the button mapping is not working anymore… So I can’t do anything except exiting the game.

Looking to /tmp/runcommand.log, I could found such messages:

UI-Console: using Audio plugin: 'Mupen64Plus OMX Audio Plugin' v2.0.0
Input Error: Couldn't find config file 'InputAutoCfg.ini'
Input Warning: missing 'plugged' parameter from config section AutoConfig0. Setting to 1 (true).
Input Warning: missing 'plugin' parameter from config section AutoConfig0. Setting to 1 (none).
Input Warning: missing config key 'DPad R' for controller 1 button 0
Input Warning: missing config key 'DPad L' for controller 1 button 1
Input Warning: missing config key 'DPad D' for controller 1 button 2
Input Warning: missing config key 'DPad U' for controller 1 button 3

This looks like the key mapping is not recognized. So I went in /opt/retropie/config/all/retroarch.cfg and could see there my key mapping schema.
I tried copying following lines in /opt/retropie/config/n64/retroarch.cfg

input_remapping_directory = /opt/retropie/configs/n64/
input_player1_a = z
input_player1_b = shift
input_player1_y = ctrl
input_player1_x = alt
input_player1_start = enter
input_player1_select = escape
input_player1_l = space
input_player1_r = x
input_player1_left = left
input_player1_right = right
input_player1_up = up
input_player1_down = down
input_player1_l2 = s
input_player1_r2 = c

Unfortunately this didn’t help.
Looking again in the log file I could see this:

Input: 0 SDL joysticks were found.
Input: N64 Controller #1: Forcing default keyboard configuration
Input Error: Couldn’t find config file ‘InputAutoCfg.ini’

If anybody has some advice on the setup, it would be great

Cheers
