Fft works, its one of the resins I got fpse. Can't use OpenGL though.
I'm not sure why it would work one one game but not another.you can try unloading the bios, wit FPSE, then load it again. To unload go to menu, misc, bios, then just hit back. To confirm, quit FPSE, open it, and you should get a message saying you should load a bios.
Other people have had that memory issue in the past. I font remember what the fix is. I suspect you may want to just uninstall then reinstall. Be due to back you mem cards and save states up - menu, misc, backup. Saves to /scard/FPSEbackup. I recommend you do NOT restore after reinstalling though. Copy the save state fold and memory card folders somewhere else using a file explorer app like astro. Then in FPSE go to menu, misc, memory card and choose the location you copied the memory card too ... Same thing for save states. Even if you don't reinstall, you may want to do this anyway so you can control weekday memory card and save state folder you're using.
Search the forums / internet for that error and you should find others with that issue.
