I purchased a retroflag GPi case 2W for Xmas and the game states of e.g. GBA: Super Mario Advance or GB: Kong where not saved when I played the games first. The reason should be that I had no rights to write to the share partition, where the roms are.

When I wrote the sd-card with the Recallbox-Image using the RPi-Imager on my Fedora desktop pc, I did not care, that there where user credentials and other Data defined with <SHIFT><CTRL>X menu from a former usage.

I used a different pc with no definitions in in RPi-Imager and now everything works fine.
