Mupen64plus & Dolphin are not working with my new GPU(had a RX 580 and now a RX 5700 XT). Most Game Gear games aren’t working either with Genesis Plus GX, but they might work with another core.
Mupen64plus crashes retroarch when I load a rom; Dolphin makes retroarch stop responding.
Any help would be appreciated.
check your drivers, I guess.
The drivers are up to date. 
In that case, we’d need to see a verbose log of the behavior to even guess.
The logs are too large. How do I upload them here?
This is the one for Dolphin:
For Mupen64plus:
For Genesis Plus GX with Game Gear:
Dolphin core needs glcore, vulkan or d3d11 for the video driver.
I don’t see any errors in the mupen log. Did it crash at some point?
I don’t see any errors in the genplusgx log, either. Can you try disabling shaders temporarily and/or try switching to glcore for your video driver?
Dolphin is working. For Game Gear I’ll just use Gearsystem instead.
Mupen crashes while loading the rom, yes. It used to just stay in a black screen, but I messed around a bit with the settings and sound started playing, but the next time I tried loading a rom it started doing this.
Have you tried deleting your core options file (or the mupen-related core options from your retroarch-core-options.cfg if you’re using the combined one)?
Maybe I’m searching in the wrong place, but in the config folder there’s only some files for specific games. I tried deleting those files and it didn’t do anything.
They should be in config/corename/corename.opt, IIRC.
The file doesn’t exist. I even deleted the whole folder and it still crashed.
But I resolved it by changing to Mupen64plus OpenGl (was using Mupen64plus-next OpenGl).
Everything working now. Thanks.
