@ion said in MGS (PS1) : Battre Psycho Mantis en changeant la manette / cassant les statues:
If you have a keyboard you can try this :
Before the fight with the boss open the RetroArch Main menu, then:
Settings => Input =>
-Port 1 Binds => Device index. Set it to disable. When you did this, the gamepad will stop responding in the RetroArch, so you have to use the keyboard.
-Port 2 BInds => Device index. Select your gamepad.
Close RetroArch (without saving the settings) and enjoy.

@ion gives you the solution to change the pad. Thanx mate.
