Hi,

Are you absolutely sure that you set your GsSPRITE parameters
correctly, accounting for the width AND the bits-per-pixel?
Chances are, your TIM is being displayed correctly in its
vertical aspect but about 50% in its horizontal...

Your 320x240x8 image is also too large to be displayed all at
once.  The limit of the Yaroze hardware is an 256x256 image,
no matter what the bits-per-pixel are.  Break up the 320x240
into 2 TIMS (e.g. 160x240).
