R4 not reading micro SD card

[DimitryIsDom]

So I have an old R4 card it's basically the original except there's a green text that says 3ds
But every time I put it in my 3ds it registers that something is in it. But it never reads the micro sd. Ive tried a couple of different firmware but it's always the same. I can't find the correct firmware I also have updated to 11.16.0 before hacking my 3ds if that even matters. I'm using a 2g SanDisk micro SD. Also I have this acekard 2 that won't even register on my 3ds. Is there even firmware for it?

Be sure if you cart support SDHC and if you micro sd is Standard or SDHC, (there are 2Gb SD standard and SDHC) and verify the format is FAT32 with 32Kb clusters.

I think both of those actually lost compatibility. Unless you install something like TWLoader to run the games from your actual sd card in 3ds
