Curious to see how it would handle Dragon Warrior 1 - I bet the dark dungeons probably don't use the scroll registers at all.

Also Ultima III: Exodus would be interesting. I suspect it's "black out tiles behind walls and in trees" effect is done through the attribute table but don't really know what it does when elements scroll offscreen.

In DW1, when you moved into a wall, it made that "bump" sound, and there were a couple different torch widths, so I would guess you are actually moving around in the room. Interesting thought though.
