Hello,
I had this working on v11 way back but hadn't used launchbox/bigbox in a while. it prompted me for a few updates and updated to v13.15 but then when trying to launch psp games using ppsspp v1.7.1 it will open up ppsspp and say "could not load game. error reading file". I know the games work because i can open them directly from the standalone emulator, but i cant open them from launchbox or big box. i updated the emulator to v1.17.1 and now it just launches into a black screen. i tried changing the graphics backend on ppsspp to dx11 and opengl and it works on standalone, just not with launchbox/bigbox.
Troubleshooting attempts:
-deleted the games from the sony psp side menu and re-imported them from their folder and that did nothing.
-checked that the file path for the emulator was looking where the games are
-checked the file path for the emulator itself was correct
At this point i am out of ideas.
