Same problem here. Mupen64plus behaves way better than the libretro previous version, but it still lags. I even suspect the audio part is the the main cause of the lagging, but I don’t know how I could prove it.

Somewhere I’ve read something about increasing the audio buffer, but in the config file in retropie 3.3 this audio buffer doesn’t appear to be there.

Update: following dankcushions suggestion, I verified that there was no joypad config file (I don’t know why, in version 3.1 of retropie this was supposed to be created automatically, but apparently it doesn’t always happen). So I entered manually to the Retroarch setup configuration -> Input devices -> Joystick and pressed the buttons in the asked order.

After that, all the emulators worked fine, except for the fact that the dualshock analog controls didn’t work (remember I’m using a twin Usb joystick, with two ps1/ps2 dualshocks plugged in). I could solve it by editing the file retroarch.cfg in /opt/retropie/configs/all/retroarch.cfg

Two parts needed modification. First, set:

input_libretro_device_p1 = “5”
where p1 above is the player number, like p1, p2, etc

Also, the D-Pad section needed to be modified (for 2 players) in the following way:

# Axis for RetroArch D-Pad.
# Needs to be either ‘+’ or ‘-‘ in the first character signaling either positive or negative direction of the axis, then the axis number.
input_player1_up_axis = -1
input_player1_down_axis = +1
input_player1_left_axis = -0
input_player1_right_axis = +0
input_player2_up_axis = -1
input_player2_down_axis = +1
input_player2_left_axis = -0
input_player2_right_axis = +0

Well, not exactly. They appear to function in emulationstation, while navigating between menus and selecting the console and game. However, after entering the game they become iresponsive with the message “twin USB joystick not configured” appearing while booting. I have tested it and the same thing happens with a wired PS3 controller.

As stated here

I was hoping that “Your joypad is automagically configured for libretro (retroarch) emulators when you configure your controller for the first time in emulationstation.”. However, it doesn’t appear to be the case. Maybe I should configure it manually, but I’m not sure how. There is a lot of information about older versions of retropie with the menus, but the names and order have changed slightly.
