So I built a setup to be portable with LaunchBox and RetroArch together on an external disk with 15 different platforms/cores. Everything was working perfect on my main computer but after moving the whole setup to an external disk 1 of 15 cores are not working anymore. In this case the Dolphin core is not even loading inside RetroArch. All other cores are loading and working.
I tried updating the Dolphin core but nothing changed.
How to make the Dolphin core work again please?
