I have this adapter http://www.amazon.com/SNES-Controller-Adapter-USB-Super-NES/dp/B002IXZ5DE which works with both my real SNES controllers flawlessly on every other emulator but RetroPie. As soon as I insert a second controller using RetroPie, it freaks out. One controller misbehaves (doesn’t matter which one) until I remove it and reinsert it and then the buttons sometimes lag.
This thing works, I know that. It supposedly has issues with the type of SNES controller used, but I have both a SNES-005 and a SNES-102 and they work great with it everywhere but RetroPie.
They show up as “HuiJia USB GamePad” and “HuiJia USB GamePad #2” even if there’s nothing plugged into the second one.
My retroarch.cfg file is correct I’m sure. I did the config for player one with both controllers plugged in and then copied everything and changed every instance of “player1” to “player2” and changed “input_player1_joypad_index = “0″” to “input_player2_joypad_index = “1″” so I don’t know what’s up.
Even though the SNES controllers are different models, they are identical and authentic.
