Yo, add BootMii as boot2 if you can, saves a lotta headache if you brick ur Wii. Oh and don't update your Wii from Nintendo after modding, u might lose homebrew stuff.

Gotta say, this is pretty cool from a 'because I can' perspective, but you've gotta be careful about security. Running such old software is gonna be full of unpatched holes. You got a firewall or some kind of network isolation for that bad boy?
