A quick one is Lego Island, just forget to put in the disc a there is black 
screen, with this patch is shows a message to put the cdrom in the drive.

Is it something like this?

create (1,1) rendertarget
clear rendertarget with black
setup ortho with no range
draw something with white
check rendertarget for any pixel drawn, if black test fails
or what?
