Oh, then no. You can use SFX without modding the console. You'd only have to mod the console if you were going to use USB Loaders, which can also run custom SFX. I'm in the process of learning how to do this myself... -_-
I can teach you [/sel fadvertisment]
Oh, thank you! I'm really glad I don't have to mod my Wii, it's 6 years old, and could explode at any moment, so modding it would be bad, heh heh.
I got my wii on launch date. It has almost exploded 3 times, has been bricked twice, and i still hack it
