Lost mupen64plus Standalone Emulator

Ikyrus

I apologize, I'm not seeing where it shows how to find the runcommand.log. I also did a search on my Pi and didn't find any file called that. I did find a file in /opt/retropie.configs.n64/mupen64plus called glide64.log:

Does that help?

@windg

Unfortunately I tried this and it didn't fix it. Thank you though!

@Ikyrus

I apologize, I'm not seeing where it shows how to find the runcommand.log.

sorry, my bad, it's the "verbose log" link on the read-this-first.

here's the link: https://retropie.org.uk/docs/Runcommand/#launch-with-verbose-logging

the important part:

Note: If launching a non-Libretro ("standalone") core, the option will not be available, but they typically will still write useful diagnostic information to /dev/shm/runcommand.log.

ie, run the game, get the crash, then download that file from that location.

Ikyrus

@dankcushions Awesome, thank you. here's what I got from runcommand.log after the crash:

@Ikyrus thanks. unfortunately that's not telling me anything other than it crashed :( it would need a debug build to find the cause. you didn't say what specific image filename you're using - the current official retropie v4.8 image?

i have no idea if there's issues with the current mp64 binaries and not in a position to test. you could try lr-mupen64plus-next which should be the next-best one to use.

Ikyrus

@dankcushions Sorry, I'm using 4.8. I have been defaulting to lr-mupen64plus in the absence of the standalone. It works relatively ok. Is next better? I was under the impression it didn't work as well on the Pi because it has more accurate emulation which makes it run slower.

dankcushions

@Ikyrus i suppose it depends on your definition of 'better'. lr-mupen64plus has been abandoned for 4 years - it might run faster in some situations but there will be lot of old bugs and inaccuracies, and they will never be fixed.

mupen64plus-gliden64 and lr-mupen64plus-next have essentially the same underlying (currently updated) codebase.

I have the same problem after running retropie's packages upgrade.

It happens with all non lr emulators.

Can you try updating/re-installing the mupen64plus emulator now ? It seems there's a problem with the latest version, but updating from binary should install a previous version, which should work.

@mitu I hate to bump an old topic but I'm also getting the same error no matter which version of mupen64plus I use:

2024/05/17,14:16:01.948,opengl_Utils.cpp:60,WARNING, "Could not query EGL extensions on this device"
2024/05/17,14:16:01.948,opengl_Utils.cpp:60,WARNING, "Could not query EGL extensions on this device"

I have removed mupen64plus from the build completely and just re-installed via the most recent update from the RetroPie-Setup script and that's the error I get everytime and it kicks me back to ES.

I have tried all three mupen64plus options in runcommand and they all do the same.

Any ideas?

Thank you.

@TPR said in Lost mupen64plus Standalone Emulator:

@mitu I hate to bump an old topic but I'm also getting the same error no matter which version of mupen64plus I use:

The 'same error' is just a generic message that the emulator has crashed and it's not caused by the same issue. In fact, you've already commended in the topic where the recent Mupen64plus breakage was reported - https://retropie.org.uk/forum/topic/35444. Bumping an old topic is just rude.
