I can scratch the surface with some speculation, I don't have time to dig into the the code personally, though.

It seemed like the glitch occurs when the player is both higher up on the screen, and in line with 2 lamps. Normally the mapper writes aren't related to where the player's position is on the screen, so to me that indicates the code somewhere is overflowing its allotted time. Possibly related to hit detection? I would look at how it's determining what value it's writing to the mapper, then if it's based on a variable that may be shared with (or interrupted by) other routines.

Is there a situation exactly like this where it works fine, in the original game? It could be a limitation of the engine, that they just didn't have to deal with because of the level design. Or just a simple mistake in the game hack. It's hard to tell from here.
