Last night i followed all the steps using the 3ds.hack guide and i had success, i tried both plants vs zombies and luigi mansion i managed to play a little before going to sleep, this morning i played some more PvZ and it freeze, so i turned it off and the nest time that i try to turn it on...
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
