Pretty interesting finding just for a difference of 1 day someone with the exact same flashcard and the exact same issue. I found this old flashcard and wanted to know if I could make it work, without any success. I've also tried custom kernels...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
