Where have you found such a screen? Can´t find something like that in Shadow of the Beast.
I only know some screens which uses interlacing to get 320*400. Or you can use raster splits in 640*200 to get more colours.
And of course our HighResMode with 640*398 and a lot of colours. http://www.pouet.net/prod.php?which=12237
