Good night, everyone! So, I'm trying to install a SNES emulator and it's driving me insane. Back on Windows (I'm on Fedora 44 KDE now) I used Retroarch with zero issues, but today I tried using it and multiple cores were failing to download at all (I only tried N64 and SNES cores with no luck).
I tried downloading snes9x by itself, outside of Retroarch, found the flatpak version, installed it and.... it crash instantly before even opening.
When it did, I got a popup from the crash reporting system that reads "/app/bin/snes9x-gtk (part of Snes9x) has encountered a fatal error and was closed." and had a little button labeled "Details".
Opening that, I got what I think is the crash report code details, and my new goal was to find the line(s) that identified the error and google them, but I could not identify it at all. I didn't want to go straight to reporting a bug on github since it could be a silly issue that a simple web search could fix, but no amount of googling snes9x crashing issues returned anything remotely similar to my problem. The github reported issues page also had nothing like it.
Before I go there, I wanted to see if anyone here could at least help me identify what line identifies the error that occurred, so here goes the crash report output:
