Hi there,

try to update your mupen64plus Emulator, because gizmo updated the configs for mariokart64 to work properly by default (like always, consider to backup your system before making changes):

sudo ./home/pi/RetroPie-Setup/retropie_setup.sh

and then update the script.
restart it after the update was succesfull and choose
“source-based Installation”
and tick only the mupen64plus Emulator.

This will reset your /opt/retropie/configs/n64/mupen64plus.cfg , so remember to set your hotkey to Exit the Emulator again.

You might also consider to unzip your roms; I think i read something about this making the Emulation slower.

With this, I can Play Mariokart64 and Mario64 smooth and without any noticeable crackles. Even the Multiplayer of Mariokart64 works now nearly fullspeed (only the race-start seems to be a bit slower).

That’s right floob, thanks for all your awesome Videos!
they really helped me to understand some configs.

The thing that didn’t work out of the box with the retropie 2.6 Image was Mariokart 64 Splitscreen (as it’s gles2n64 by default).

Luckily gizmo98 fixed that as described here

Mupen64plus (ricrpi branch)

I don’t know if this also fixes the Audio issues of mike17, but at least I have no Issues with Mario64 and Mariokart64 with the updated Mupen64plus.

What amp is the power supply you’re using? It could be as simple as the pi is not getting enough power. It also could not be but its something to check just in case.
