                 DROP SHADOW TEST


This is a crucial test for 240p upscan converters.
It displays a simple sprite shadow (32x32 pixels)
against a background, but the shadow is shown only
on each other frame. 

On a CRT this achieves a transparency effect,
since you are watching a 30hz shadow on a 60hz
signal. No background detail should be lost and
the shadow should be visible.

- The user can toggle the frame used to draw the
shadow with SELECT. 

- Backgrounds can be switched with button I.
