I was trying to get custom CSPs on ssb4 until I ran into a problem with converting the .nut file into a dds file. I opened the InjectPack in a command window and typed "nut_check.py chr_13_Sonic_09.nut" then pressed enter but got an error that read; "Traceback (most recent call last): File...
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
