Yeah that's what i meant with I've found and loaded the default BIOS (SCPH1001). Sorry if I was unclear
The problem is that the process still dies when trying to load a game. HLE is disabled, and the settings are saved as default. The app still crashes when trying, saying something like "The process terminated unexpectedly."
Gonna try with another game and/or another BIOS when I get home from work. FPse also just updated itself, so I hope my problem might have been worked out!
Posting again when I've tried some more!
