Sorry, I noticed that the #’s where there, but they weren’t when I tried the setup. Regarding the jstest I have the same number on the buttons on both players, except p1 @ js0 and p2 @ js1. And the same axis on the joysticks.
I’ll have another go at it tomorrow and look at that code you pointed out now.

[quote=93678]Is the first set of mappings exactly as seen in the cfg file? As in, are the #’s there? They shouldn’t be. You have to remove those.

So both sets should probably look the same as what you pasted as working except

input_player2_joypad_index = 1

You can use jstest to figure out which button is which to map to the button in retroarch. But if you say that the uncommented button map works for player 1. Player 2’s should match.
