Every time I try to play a game, after a certain while, the screen will lock up and emit a constant buzzing noise. 2 different consoles, Wii U, and regular Wii. The regular Wii has d2x v6 (don't tell me to upgrade - any others don't work) and the Wii U has d2x v10 beta53. Could it be related to the fact that I'm using flash drives (hasn't done it before) or is it a cIOS problem / hardware problem? It's really annoying. Any help is appreciated.
