I would like to update my non retina game to use the wide screen in the iPhone 5, is it possible to use a 568x320 sized OpenGL window?
I have now compiled and got my game working at 568x320, all I had to do is include the Default-568h@2x file and do this in createFrameBuffer
[self setFrame:rect];
[self setBounds:rect];
[self.layer setFrame:rect];
[self.layer setBounds:rect];
