I'll try to be very short in my questions to not take your time.
I got my new wii with 3.4U and wiikey 2.
1. Should I downgrade to 3.2u ?
2. I'm having problems with super mario galaxy and I was trying to change the speed read disk from 3x to 6x. The config disc does not work and I do not have starfall installed. How can I make the config disc work ?
3. It does some at 6x by default ? Is there a test for it ?
