Level information is loaded for each level 0-9 (with 0 being the overworld). The Level Info Directory contains the addresses of level information blocks for each level; I have calculated their offsets here for your convenience. Much of the level information blocks is not decoded yet.

Starting Locations

The starting location for a level is a screen number, found at byte 47 from the start of the level information block for that level.
