door pointers


You mean the door pointers, right? They determine where the door leads, so without them being set up correctly, the door won't work too well 

As for how the door pointer works:
- Last digit of X location: level the door leads to (0: 1-1, 1: 1-2, 2: 1-3, 3: 2-1, etc.)
- First digit of parameter value: area in the destination level
- Last digit of parameter value: page in the destination area
