lr-gpsp not (only partially) working
I did a bit more digging and went down a bit of a rabbit hole.

There's a file called /opt/retropie/libretrocores/lr-gpsp/game_config.txt
It should be located at /home/pi/RetroPie/roms/gba/game_config.txt, because that's where lr-gpsp will look for it.

It ONLY gets used if there ISN'T a compiled-in entry for the game you're loading.  In the code snippet, load_game_config_over tries to find the compiled-in entry and load_game_config reads from the game_config.txt file.
   if ((load_game_config_over(gamepak_title, gamepak_code, gamepak_maker)) == -1)
      load_game_config(gamepak_title, gamepak_code, gamepak_maker);

Well, I edited so that it didn't include an entry for the file I was having problems loading.  Then it loaded /home/pi/RetroPie/roms/gba/game_config.txt, but it still crashes in the same way.  I guess that means that game_config.txt isn't the problem (or maybe that the settings in it aren't correct).

Here is the output leading up to the crash.

The rom isn't incompatible. I can load it by launching through retroarch (as I described in my posts before).
My point was that if another (known working) game loads then it appears to an issue with the emulator/front end/rom and not specific to the FPZ and therefor the thread belongs in the relevant forums for those and not here. If you are having issue loading a ROM that would otherwise load and run fine on a generic Retropie build and for some reason just fails on the FPZ then it would belong here.
