Getting generic micro SD cards to work with Picoboot?

[ThaKarra]

Hi all,

Just wondering.. Does anyone know of any methods to get generic micro SD cards working with Picoboot?

I have a stash of cards I picked up off Aliexpress that are all 64GB in storage. However none of them work with my modded GameCube. I've tried formatting them to both exFAT and Fat32 but I've had no luck. If I copy the exact files over to a Sandisk card then it works perfectly. - I've also tried deleting the volume of the 64GB cards and creating a smaller 32GB partition.. But no luck with that either, the SD2SP2 adapter just doesn't seem to recognize and it boots straight to the default GameCube screen.

I just want to point out a couple of things.

- It's nothing to do with the Pico mod installation, as mentioned above it all works perfectly when I use a proper branded SD card. I can also verify the installation when I hold the down D-Pad and power on the console.

- I've also verified the reading/writing of the SD cards, so they aren't fake.

Any tips or information would be greatly appreciated
