i did this....as i had softmii installed...
i softmii'd anothewr one, all went well, BUT, need for speed undercover would not run from disk channel, but did from backup launcher, reburned too, still wouldnt work,
even though it did on MY wii, which had starfall on it till i upgraded to softmii preloader 2.8.
it was bugging me how 1 worked and 1 didnt, so..
i upped mine to 3.4, and now no originals play through disk channel, so i think i need to redo softmii all over again starting with downgrade..
homebrew channel still works for me..
im gonna do this once home..
