I'm using devolution (obviously since nintendont isn't finished). I verified it first on my Wii. And it started up just fine. I then took the SD card out and put it in my Wii U. Went to USB loader GX, and selected the game. But it didn't work. I just got a black screen. This is strange since my other gamecube games work fine on the Wii U. I followed the same method for verifying them. What's going on? Does anyone else have this problem?
