Hacking R4 card stuck on loading screen forever

[Maglata]

I know that the problem is from the kernel. I've been searching for days but I couldn't find one. Please help me out all that says on the card is "R4 SDHC Revolution for DS (NDSL/NDS)" I can't upload pictures right now but if someone can help me I'll send them the pictures in PMs.

Hello. Size of the card, and file system?
Format it to FAT with default allocation table.

If you can, post a print screen of your file structure on your SD card.
