Using paraLLEl-GS in LRPS2 crashes/shuts down Retroarch

Libretro Cores
#1

Hey all. I’ve been having rotten luck with LRPS2 and paraLLEl-GS.

I load the core. Boot into it. Change Video output to paraLLEl-GS. Exit the core. Try o restart it or play any game and Retroarch decides to just shut down.

Would really appreciate if anyone could help,

On my machine, LRPS2 crashes each time I load it twice without restarting RetroArch first. So, in your case, what I would do is, in order:

  1. Load any game on LRPS2
  2. Change renderer to ParaLLEl-GS
  3. Close the content
  4. Restart RetroArch (the entire app, not only the core or content)
  5. Try to load a game again.

See if that helps you.

#3

Thanks for the suggestion but, unfortunately, same issue.

It’s honestly so frustrating since I found only one other person with this exact issue (on reddit) and there was no response to it.

#4

It looks like it’s getting past the ParaLLEl-GS initialization stage and then failing later on with this:

[libretro ERROR] IsoFS could not find the root directory on the ISO image.

Does it have that same error for you with other renderers?

EDIT: also, which game are you trying to load. I don’t see that anywhere in the log.

Can confirm. every time ParaLLEI-GS is activated retroearch crashes silently to desktop. Its been happening since march or april i think, i have an older version that works but since there is no crc/version and it only shows as “LRPS2 (1)” dont know wich version is the one working.

I’ve tried multiple games and they all crash. The logs above are me just trying to start the core (boot screen) after loading it.

It works fine with the Vulkan renderer.

So it’s not just me :pensive:

I’m surprised this hasn’t been reported much.

starting the core without any content doesn’t work for me, either, but games do.

#9

I tested here and could boot fine without any content, even under ParaLLEl-GS. I’m using Linux though. Could it perhaps be some issue with the BIOS used?

could be, or something else :man_shrugging: I’m on linux, too.

I’ve tried different Bios. Same issue.

I plan to try something else later today. Gonna try and mess with the AMD Radeon drivers.

Unfortunately that didn’t work either.

I did a total wipe of my AMD drivers with DDU and tried a fresh install. No luck.

And speaking of luck, my CachyOS Linux install is having issues when using Vulkan with RetroArch. The frame rate drops down to under 10. Unusable. And I’ve seen multiple people report this.

What rotten luck :pensive:

Have you tried adrenalin 25.3.1 or earlier driver? and here is the old core i have a backup, for me this works fine.

https://www.mediafire.com/file/vrnv79hz8oj7ahh/pcsx2_libretro.7z/file

could yo test this?

I suspect is an amd driver issue.

#14

Well, driver support for amd/ati gpus has always been very quirky, so that wouldn’t be surprising. People might think that’s an urban legend because commercial games (usually) run ok, but that’s only because commercial games can afford running tests on a wide range of gpus.

#15

This version of the core works!!!

How old is this version and what is it missing compared to new one?

Thank you my friend!!

#16

I have one device with an AMD card (iGPU), and the latest LRPS2 works fine there, on Linux, RetroArch 1.21 (AppImage). If enough people share their configurations and if it works or not, there’s a chance to pinpoint what’s exactly triggering the issue.

#17

Well so far it looks like no one with Linux is having any issues.

I believe the couple of posts I saw on Reddit were using Windows like me.

#18

hunterk uses Linux and can’t boot into the BIOS, whereas I can. It’s probably not only the OS’ fault.

#19

works fine on my end on windows 10 but on Nvidia and Intel CPU

here are retroarch and core configs

I’ll keep the core provided by cuyo saved and keep using it until one of the core updates finally starts working.

Thanks again Cuyo
