older wiiu version support

[Reual4412]

I don't necessarily need it, however a user does. Simple jest of if it is he managed to brick his vwii, and he is on 5.4. He cannot update his wiiu since vwii is bricked, and according to him (I don't know since I got my wiiu on 5.5.1) mocha doesn't work on that firmware, which results him being stuck.

he has to update it to 5.5.2 manually then
