Can I remove a tileset from NWMap?
You can. Open up the NWMAP.INI file. This file contains the tileset definitions. For each tileset, there are three lines: the tileset name, the tileset bitmap filename, and a number identifying the group mode/smart mode scheme. Just delete all three lines of the tileset you don’t want anymore, and restart NWMap. Note: If this file gets corrupted somehow, just delete it, and NWMap will automatically construct a default version.
