it took me forever to figure it out, but it works for me.... so here goes.
if you have an r4 or m3 and possibly a few others, get the R4 wood firmware and swap it out for the kernel 1.18 firmware. It'll work a bit different, i haven't figured out how to use any cheats with it, since it's...
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
