Layer 3 Circle, and Exits???

Besides making sure that the 6.1 flag is checked in "unknown bits" in the layer section for the map in the level editor, you need to set that circle thingy in the map's Entrance Event.

Hidon's Cave map 194 take a look at the entrance event. It shows it using the address of 174B2 which is CB/74B2. So looking at that in the event dump here you'll see the first thing is:

CB/74B2: 63 Create spotlight effect with radius 20

So if you have this set in your maps entrance event, and have the 6.1 flag checked, it should do it. But sometimes you'll need to also put the command in for any events that re-load the map for like an exit or whatever, before the screen fades in from dark.

I might just be tired and reading it wrong xD. But is this how to take it off? or how to set it bcuz I want it off. And I'm reading it as setting it xD.
