DYI sd gecko error emulate memory card slot A

[curcius]

Hello colleagues, I come to ask for help with my gamecube that I installed picoboot and adapted the micro SD card reader to the memory card like a homemade SD Gecko, but I am suffering from an error and I have tried everything without solving it.

I put the gecko sd in slot B and I emulate the memory card but it doesn't work. It always gives an error. I've tried several micro sds, and it always gives an error.

The games run normally without problems, when I put it in slot A I can use the virtual memory card, I can format it and everything else, but I can't use it in games because it asks for slot A.

My console is a dol001

Error message follows when I try to format in slot A

Slot B when the gecko sd is in slot A I can format it, the virtual memory card appears normally but I can't use it in games.
