Welcome aboard m8 and any questions you have about things, just post them in the questions section under bully modding and we will do our best to answer them.
Just to let you know tho: I am positive that modding bully on the wii can be done since I have already modded bully on ps2 using some of the mods Steman and I have created and can vouch that console modding is indeed possible, but since I do not own a wii....I have very little knowledge about that particular console.
Most of my mods tho will be concentrated mainly on the pc version but I will also be doing a ps2 port of all those mods as I get the time and will do work on them.
