Mmkay, I brought a pre-modded Pal Wii last summer but since I've only been buying original Wii games since then, I've had no need to find out what chip is in it (I didn't ask when I bought it because I'm pretty inexperienced with hacking - I've no way of contacting the seller now either). Now...
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
