Huge thanks to reader Xiao for the translation on the next bits!

- channel for online aspect

Now, some points of interest from the scans.

This online screen clearly shows a green A button and a red B button. Could this mean that there will be Cube controller support?

Also, a confirmation on Baby Peach. I have to back up my employers at NMag on this one. NMag claimed Baby Peach was in the game (among other things), Nintendo shot down their info, and now we have confirmation.
