i finally managed to grab a "cheap" wii u with a game pad to mod, i didnt want to use the one i bought new incase things went really wrong.

has any one done these for the Wii U?
i was mainly looking at DS and Gamecube support with upscaling over hdmi. i hear this can be done.
i went out and grabbed 2 SD cards (one for another project) and a reader to get this going. i'm just about to make sure its fully functional before i attempt, it just came in yesterday
