So I have.received my rg300 the newer snes style I have flashed a 32gb card with the custom fw but for the life me I cannot access the internal memory I have flashed 2 cards and no matter what I try I just cant access it. I have tried connecting the unit through 2 usb c cables my laptop wont recognise the unit at all in usb storage mode I get a message telling me to mount the partition. I have also tried through a card reader and my laptop wont allow me to open the card as after flashing it's not the correct format. I have tried with the original fw on the original card and have the same.issue is there anything I can do?
