Hmm this looks like a very interesting app. Basicly this allows you to experiment with your wii all you want and if something goes wrong, you just throw away the nand dump right? So this really only depends on the boot1 that is present on the wii being used right? I don't think it's even possible to damage this file, but as long as your wii still has a boot1 and a bootmii boot2 on it this app can run right? Even if the rest of the nand is completely blank or corrupted? Anyways thank you all the people working on this for taking the time to make these great apps! I'm really looking forward to this.
