I’m not sure what caused the games to be in datei format and not nsp-datei format and I’m having issues installing them now that I have my new SD card. Does anyone know what caused this and how I can fix it. I’d really appreciate the help especially because most games are like this now.

was ist 00 01 und 02 fuer ein spiel?
Das ist Monster Hunter. Sind aber sehr viele Spiele betroffen. Gerade die Spiele die über 4 GB waren sind betroffen. Verstehe nicht warum, aber muss wahrscheinlich nochmal die nsp ziehen.
