I have the wiikey2 installed. And I just updated the firmware to 1.3.
And I have problems running smg2.

I use dvd+r Verbatim discs. It worked fine for the update.

I did see the game pop up in the wii cd channel. But when I pres A then it is supposed to load the game. But instead the screen stays black.

I'm not sure if it is because of the disc or something else.
