I installed the new homebrew channel and it solve my problem. The version of scummvm that is in the apps package has a smaller intial screen size, so I get the full picture. just thought id let anyone who also had this problem know.

Ive tried both the gamecube controller and the wiimote versions and I have the same problem. The outside edge of the screen on all four sides is unreadable. I think it is a size over run issue. Has any one else experienced this? any solutions?
