I rewired it today. Here is what happens:
1st Try
1. Turn on the cube without an SD card
2. Error messages flash like they should
3. I have tried two things from this point. If i hit the switch, it freezes. If I put in an SD card, The messages stop flashing.
2nd Try
1. boot up with an SD card inserted
2. cube freezes instantly, or the error messages don't flash.
I've checked all my wiring.
The Wiikey works on my Wii
I have the switch connected to 1.9v.
At this point I'm about ready to have someone do this for me.
