i have a sky3ds blue button model cart, for some reason i get lockups (sound goes away and once i change scenes the screen stays black forcing me to reset)on my lexar class 10 16gb sdhc micro sd card. i have another lexar thats a class 4 4gb sdhc micro sd card that hasnt given me any trouble...
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
