I have some trouble configuring my PS DualShock 3 in Retropie. I managed to correctly pair, connect and configure my controller on my PI 2 (OSMC/Retropie) but as soon as a PSX game is launched, the emulator seams to take the gyroscope information as a joystick input (and one knows that Medievil couldn’t be played that way 😉 )
I did it by myself. I think i made it not in the cleanest way but that seams to work with me 🙂
I was looking for the script that convert controller information to a key. I find this file in “/opt/retropie/supplementary/runcommand”. Open the Joy2key.py file and comment the lines from “if HEX_CHAR…” to the end. This previous condition seams to send hex character from gyro/accel, by commenting those line, the python script ignore the motion information and then problem solved !
