[HOW-TO / TESTING] RetroPie on Vero4k

well you don’t need that since it uses an external executable, to get this to work you have to go:

Setting->Add-on Browser->My Add-ons->Game add-ons->Emulators and enable the emulator you want.

After that you add a source, by navigating to you roms folder. From there you can click the rom and it should open in the emulator of you choice. If you are going for Mame-rom read the instructions in First post about File association and libarchive.

Uninstall the Advanced MAME launcher, since it’s not needed.
