[Solved] mupen64plus crashes back to EmulationStation (x86 system)

mitu

Try un-zipping the ROM or use a .n64 ROM.

Panja

I'm not using zipped files, I unzipped them.
These are verified roms...
z64 should be compatible as per wiki.

I can try .n64 when I get back to my machine.
But I don't think that's the issue to be honest.

Panja

I don't want to sound rude but I really think the z64 file is not the problem.
As far as I know z64 is supported with all emulators and is the prefered extension for N64 games.

No-Intro and other rom rips are all Big Endian rips:
Little Endian (.n64)
Byte Swapped (.v64)
Big Endian (.z64)

So the error and crash should be coming from something different.

You're right, for some reason I thought .z64 is a zipped .n64. I tested initially with the .n64 ROM version and didn't get an errors. But I also got a .z64 - validated it against the No-Intro .dat file - and I get no errors also. The game starts the same message shows in the log file for both ROMs.

Do all your N64 Roms behave similarly or it's just one (Super Mario 64) ?

Panja

Thanks for checking!
It's all roms I've tried (around 6).

Panja

Indeed it's the problem I'm using ALSA instead of Pulse.
Edited /etc/pulse/client.conf and changed back to ;autospawn = yes
Now mupen64plus runs.

The thing is I need to disable Pulse on my machine because it's not working properly.
After a while playing and changing emulators the sounds begins to lag behind.
Running only ALSA fixed this problem for me.

Is there a way I can run mupen64plus with Alsa instead of Pulse?

mitu

I can see 2 options you can try:

Make PulseAudio work - try to make it run realtime and see if that makes a difference: https://medium.com/@gamunu/enable-high-quality-audio-on-linux-6f16f3fe7e1f
Switch to ALSA in Mupen - modify the /opt/retropie/configs/emulators/mupen64plus/bin/mupen64plus.sh startup script and set SDL_AUDIOPLUGIN=alsa instead of pulse around line 447

Panja

@mitu

I’ve tried to make it work and did not succeed.
I can give that link a try though.

The second option is maybe better for me.
Though when changing the file will it be overwritten again if I do a RetroPie update?

Yes, when mupen64plus will be updated, the file will be overwritten.

Panja

@mitu

Ok. I’ll have to make a script than to change it to Alsa.

But I’ll give Pulse another try with the link provided first.

Thanks!

Panja

@mitu

Quick update.
Changing line 447 in /opt/retropie/emulators/mupen64plus/bin/mupen64plus.sh fixed my problem. I have changed pulse to alsa.

Further more I've created a simple script, named n64audio to run at start/boot.
In this script:

#!/bin/sh

sed -i 's/pulse/alsa/g' /opt/retropie/emulators/mupen64plus/bin/mupen64plus.sh

Made the script executable sudo chmod +x n64audio
After that sudo crontab -e
And added the line @reboot /home/retropie/n64audio

Now after every reboot pulse will be changed to alsa in the file /opt/retropie/emulators/mupen64plus/bin/mupen64plus.sh , if the line pulse exists.

So if I update RetroPie and mupen64plus gets updated and overwrites my file (and put pulse back in to play) it will be overwritten on the next reboot.

Again, thanks for all your help!
