Debugging; it does not appear to be hdma related :-( Can't see any hdma usage 
in the problem area.

From linked forum post another game with a similar problem (bottom of screen) 
is "International Superstar Soccer 2000.gbc"

The other game in the post is "Top Ranking Tennis.gb" which is a flashing issue 
(and may be a different problem.
