I've attempted to put a Message Name on a dummy map ($10B) and even if the Exit Field that lead into that map has Show Message enabled, no message is shown. Do you have any idea why? My theory is that since it's a dummy map, many elements (strings?) are missing and Message Name is one of them.

How it work is if message name is enabled on the exit, the map will show the string that is set in the map data. I think if it point to an empty string (00) it will display nothing (not even the blue text container). The map data only has the string ID, it does not contain the string itself. Every map has the same 33 bytes structure for data. This seems to be sort of a limitation by the game. I'll have to check in code to see if there is any limitation.
