Console always missing first line
The first line of the console is never displayed, it seems to be a bug in the console. This is not a matter of the TV overscan, the first line is never displayed no matter how much yoffset specified, you have to always printf \n at the start. See: User:CarstenK/ConsoleNotes
Wrong aspect ratio... 16:9 widescreen or normal.... PAL black borders?
Maybe libogc and GX is just at a low level where it actually doesn't handle non-square pixel aspect ratio, either that or there is a bug in it? This maybe might explain the black border issue some PAL users are reporting too.
Please see User:CarstenK/Screen_aspect-ratio for theory and discussion.
