Still a prototype. I'm using integer versions.
Added a snippet of code that attempts to identify world map locations where an exit will drop you off at. One would hope this lets you know where you're teleporting to. Numbers in the bottom right may be of assistance. Additionally, for room exits, I invert the colors if it's 0x3F, and instead show a number from 0 to 3. That's the selector for our world map thing.
Then again, I don't have much experience with these glitches about somehow making use of alternative exits, so I haven't checked how viable the numbers I'm showing are. Also, there is a *known* failure with my script when we're talking about the Maze, as for some reason, the standard 0x3F I expect to see isn't showing up, yet it exits to the overworld. I have things to look at.
