Is there any way I can get the vanilla level maps in blender?

Hi, I'm working on a romhack for a different game with some custom maps, and I want to use a few levels from the vanilla version of this game for it. However, I do not know how to get the map files into a format that is supported by blender. I believe the map files for this game are in a ".dif" format, which obviously is not compatible with blender.

Does anyone know a method in which I can convert the files to a format supported by blender (.obj, .dae, ect.), or does already have access to the map files before they were converted to .dif? Any help would be appreciated!

this addon for Blender lets you import and export .dif files directly

Thanks!
