If this is all overwhelming or too much for you....
we also have a hard mod section that show the type of mods available.
Hardmods are very easy and requires almost no maintenance
and not really affected by wii game update except for the region compatibility(wii fw 4.2)
with the new Hard Mods, its almost impossible to Brick your wii, if you are worried about that.
only thing with hardmods is they are NOT FREE, but the recommended way if all you want to do is play games with dvds or hard drives without having to learn all about how or to have to maintain your softmodded wii
