Mupen64plus_next_libretro "failed to load content bug"

RetroArch Windows devices
#1

As of 1.9.2 using mupen64plus_next_libretro if I load an N64 game it loads fine. However if I close it and try to open another n64 game I get “failed to load content” dialogue. (This is for games that are known to work well)

Windows 10, Retroarch 1.9.2, Vulkan, Achievements On, Slang Shaders On.

Here’s a log:

#2

Are your games zipped? If so, does it make a difference if they’re unzipped first?

#3

Yes, unzipped same behavior. I think this started when I updated to 1.9.2. Don’t know if it’s Retroarch or core causing the problem.

#4

It doesn’t load anything for me on Android either.

#5

This bug is strange is odd.

I created a new 1.9.3 installation in a new directory, downloaded the most recent mupen64plus_next_libretro core, created a new playlist and tested a few games. Behavior was as expected - Open a game, close it, open another one, it ran fine, closed it, opened another one - no problems etc.

This is where I am super confused and I’m hoping somebody else can think of something I can’t to explain this.

I deleted my original RetroArch directory, repeated the steps above EXACTLY and I’m getting a similar bug to before. The difference being Retroarch is now crashing rather than showing the “failed to load content” dialogue it previously showed.

The strangest part is, if I change that directory name by one letter, the bug goes away, and it comes back if I change the directory.

Is this a regedit windows thing? or something at the driver level? I feel like I’m banging my head against a wall trying to solve it.

#6

Update - Changing the name of retroarch.exe to retroarch1.exe also prevents the crash. any idea what is causing this?

#7

No, that’s definitely strange. I seem to recall something sort of like this a few months ago but I don’t recall any of the details. I’ll ask around and see if anyone else remembers more.

#8

Thanks, I appreciate the help.

#9

Just checked and it’s no longer happening. I don’t know what fixed it as I didn’t update update Retroarch or nvidia drivers and as far as I can see Windows hasn’t installed any updates since I last posted. Strange.

Hunterk, did you hear anything back when you asked around? I’m curious what caused it in case it ever happens again.

#10

no, sure didn’t. nobody remembered it happening before :confused:
