A fork of the game engine modified to let the user create entities with their mouse that generates the tags for you and saves them to the .dat file would be helpful, even if you just kept it to yourself, it would simplify the process a lot.
A simpler solution could be done maybe with 2d tiles where you draw it like it would look on the gameboy and it generates the basic geometry of the map for you to go in and tweak by hand, to remove some of the busywork. That'd be kind of a band aid solution though
