I just received my new R4 SDHC Gold Pro in the mail and after some difficulty I managed to find the kernel I needed (I believe). I'm running the card on my 2DS Ver. 11.3.0-36U and I can get DS roms to run perfectly but I tried a 3ds rom and it wouldn't run at all. Just seemed to freeze. The kernel I downloaded had the file name "R4i-V3.9b English". In case anybody is wondering as well I'm posting a picture of the card I have. Any help would be much appreciated as I've gotten a Sun/Moon rom that I would really like to play.
