Subject: Re: MM game code corruption when Willy drops off the bottom of the s
One more detail - if Willy drops off the bottom of the screen in Manic Miner whilst his x-coordinate* is odd, then the first character of the scrolling message on the Title Screen is also corrupted (i.e. the value at #9D00 is overwritten by one of Willy's graphic bytes). However, this doesn't occur if Willy drops off the bottom whilst his x-coordinate* is even.
(* The x-coordinate of the left-hand half of his sprite.)
