Thanks for the reply. I managed to get around the problem – seems that merging the micro sd card with internal memory (formatting as “phone storage”) causes issues on this device. The latest problem I had was with Duckstation which wouldn’t import its BIOS for whatever reason. Formating the SD card as “portable storage” fixed all the issues I had. Seems Anbernic has done something wierd with this machine as all others I have are configured as “phone storage” with no issues.
I’ll happily join beta if it’s available.
