Hello!
I am new here, and am interesting in customising my 3DS Theme...
I was poking around with the program given, and I managed to edit SOMETHING... I selected the Customization Tool, changed the Kingdom Hearts photo into something of my own, and "Save" it into my 3DS SD card... But still...
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
