Multiple (same) controller with differrent configuration

[jacksonfylle]

Hello,

One of my controller doesn't work as i wish.

I've two controllers DragonRise
pi@retropie:~/RetroPie/roms $ lsusb

Bus 001 Device 005: ID 0079:0006 DragonRise Inc. Generic USB Joystick
Bus 001 Device 004: ID 0079:0006 DragonRise Inc. Generic USB Joystick
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The thing is one of my joystick is upside down (arcade cabinet) and i cannot really modify that.
So when i configure the first and the second joystick, after a reboot or when i launched a games, the configuration of the second is wrong. For examples when i go left i'm going to the right.
EDIT: specially with n64 system because it doesn't use retroarch.

I've tried to modify this file /opt/retropie/configs/n64/mupen64plus.cfg And setup different value for the X axis but it doesn't work.

i think mupen64 only read the file InputAutoCfg.ini and the probleme is : in this file there is no distinction between controller 1 and 2.

I hope you understand my problem, sorry about my english.

EDIT: Solved

Edit the file /opt/retropie/configs/n64/mupen64plus.cfg
And make sure this option :

# Controller configuration mode: 0=Fully Manual, 1=Auto with named SDL Device, 2=Fully automatic
mode = 0

is set to 0
