The patch helps in that the 640x185 image no longer locks the system up
and it displays something, thanks! The image is corrupted however.
Rather than trying to describe it:

(I'm refraining from comment about the logo itself ;-)

As well as the wrapping, the blue colour to the left is also corruption,
and marks the edge of the screen.

I suspect the rotation function has a bug...
