Show me a LEGALLY hacked Wii, and I'd think you were cracking up.
The RawkSD program can be used for reasonably legitimate means, mainly custom songs and DLC that you own, but it is rather old, and the developers have since moved on to other projects. You may be interested to know that @Larsenv and @DarkMatterCore are trying to tackle the problem of adding customs and DLC back to RB2, and I have been doing some tests of my own to try to overcome the limitations in vWii (since RawkSD never really supported vWii, anyway). We're using alternate methods to atempt this, so please stay posted to my Rock Band Customs thread for updates on the matter.
Heh XD yeah good point about the hacked wii >.>
I still have my original WII, and I just got a cd copy of rock band 2. but i think because my IOS 37 is a CIOS it still won't work. but who knows. the disk arrives today.
I know there are very very complex ways of installing customs to rockband 2. but I never go them to work.
