Here's an exemple:



Moving to the next screen, the overlay on top remains, but exiting that room it disapears as you move to the other one. Hopefully this is fixable, even if all BG2 on top rooms all need to be entered manually to get that effect everyhere.

So in theory, you should be able to "replicate" this hack for every room with

$02/8B3D F0 -> 80
(0x10B3D F0 -> 80)

However, there must be a very good reason why it's done this way, as the result of no-branch is storing a value into $1C, which according to Math's docs it's

$1C Main Screen Designation ($212C)

For now, Seph, please apply the hack above and play around with the rom to see if there's any "weirdness" happening between transitions (check stairs too). I have a slight feeling by skipping the code it won't go from "on top" to something else properly should you need that. That being said, we know where the code is so we can "code" a workaround to specify all the rooms which you need this effect for.
