Open all Levels in DMX-1.3.2-dkz02. This patch was released in the "golden" era of DMX-1.3.2-dkz02, means when it was originally released.
This patch opens up all levels in the game, but you need a new game. At least the "static" levelchangers are set up, not the one you get as result of a quest or questline, or by using objects.
Unpack to the main folder of the game.
