Turn off the set up automatically?

So I have a specific core that I do not want updated when using a quick launch icon. How do I set it up so it doesn’t ask to set up automatically? Just use the emulator core already in the system instead asking for wifi to update?

I believe the way you would do this is to edit the action.config file for the system in question so that it points to your emulator core file.
If the GS is asking for auto-setup, it means it cannot find the core in the location specified as “ROM_SO”, so it will use the link for “SO_URL” in action.config to download it.

For instance, I keep all my cores in ~/apps/emulators.

An example action.config. This one is for GBA:

LAUNCHER=retroarch -L
