[Solved!] [Pi3 RetroPie 4.0.2] Some N64 games crash when trying to load state using any of the mupen64plus video plugins

[ErayMan]

Launching Banjo-Kazooie works just fine and I can play for hours. I can save state (using Select+R1) but if I press Select-L1 to load state it crashes to emulation station. I know the save state works because a .st0 file is created for banjo kazooie.

Save/Load states work for all other console (snes, playstation, nes, etc) and even some N64 games like Mario 64. But Banjo Kazooie simply crashes.

I am running a downloaded Retropie 4.0.0 image (upgraded to 4.0.2 via binary update; but had issues on both). The only thing I changed was:

1. the ”disable_overscan=1” in /boot/config.txt to remove black bar
2. I configured dispmanx through the retropie setup script (But I tried to change it to GL, SDL, back to dispmanx, etc, inside the retropie configs for the n64 without success)

Log found in /dev/shm/runcommand.log:

Any help or pointer to where I should look would be appreciated :) thanks!

@ErayMan try changing the audio plugin

I mentioned it here a while back: https://github.com/RetroPie/RetroPie-Setup/issues/1061 but must have gotten lost in the weeds, I haven't tested it lately but likely a similar issue.

Same issue here. I tried with my manual Installation and a new installation with the latest image. The only thing I changed on the latest image was installing ps3 drivers and configuring the controller. Crashs with all mupen64plus plugins when loading a save state (but not with all games).

Will try changing the audio plugin, thanks for the hint.

@herb_fargus Thanks for your help!
I am having trouble changing the audio plugin though...
I'm trying to change /opt/retropie/configs/n64/mupen64plus.cfg
This line, from:
AudioPlugin = "mupen64plus-audio-omx.so"
To:
AudioPlugin = "mupen64plus-audio-sdl.so"
but every time I start the mupen64plus the file automatically gets updated and reverts to "omx.so"

I tried changing it from the "configuration menu" in the retropie setup script, in the n64 section, but it seemed to do nothing. (Is it only good for libreretro n64 emulations?)

I also tried to put inside /opt/retropie/configs/n64/retroarch.cfg:
audio_driver = "sdl"

to no avail.

I see some "omx" logic inside mupen64plus/bin/mupen64plus.sh but I'm hesitant to change that.
Thanks again for your help, and I'm sure it's just a small overlook on my part

Open /opt/retropie/configs/all/autoconf.cfg snd set mupen64plus_audio=0. You can also try to use glupen64 libretro core.

@gizmo98
Alright it works now! Thanks to your suggestion, I was able to upate /opt/retropie/configs/all/autoconf.cfg
and set "mupen64plus_audio=0"

The crashing issue on loadstate is gone for all n64 games :)
The audio is a bit crackling here and there but for more stability, I guess it's a fair tradeoff.

Thanks Gizmo98 and Herb_Fargus!

Works also on my end. Thank you!
