Reset config on a specific core

I’ve messed up the settings on PPSSPP and now nothing will launch. It just resets when I load a game.

Is there a way to reset to default settings on a specific core? Or do I have to reset everything?

Thanks in advance.

You should be able to delete the lines in the below file related to the core:

/storage/.config/retroarch/retroarch-core-options.cfg

The next time you start the core, it should have everything at it’s defaults as if you started it for the first time.
