returns -1 if the cell isn't located in any room, otherwise it will return the index of the room. However I haven't found a way to correlate a room id with a room name or type.
Heck yes did use Notepad++ on the save file. I do need to make my level editor 1.20 beta release for new version, had my head buried in this file for a while. It's Christmas, sorry If I posted in wrong place but would love some feedback for my editor!
