LÖSUNG: Der USB Stick muss mit FAT formatiert werden. Die Formatierung ExFAT hat nicht funktioniert.

@diegus83 No, i mean it was never implemented in the backend of FBNeo, which is the part retroarch (which is a frontend) use. The standalone windows version of FBNeo work around this by having a frontend feature, but retroarch doesn't have this.
