Hey everyone.
Today I am writing this, because after extensive research on this device, I couldn’t find ANYTHING about how to get roms onto a sim card to bypass the sad 6GB left on this device.
I purchased a 128GB sim card on amazon, and checked out the internal memory of what is already in the device. I found it was formatted as FAT32, so I formatted the sim card as FAT32, put it into the device, and error, card format not supported, please format again.
So I formatted as NTFS, same error…
I eventually formatted as FAT, PLAIN FAT, and put a single gba file in the root directory, and that seems to work.
I did format it in linux, windows didn’t seem to work for whatever reason.
Hope this helps someone.
