D2X-XL is an OpenGL-port of Descent II. Supported platforms are Linux, Mac OS X and Windows.
Quote:
v1.15.89
Fixed: Faces containing see-through areas became completely transparent when lit with the headlight
New: Added a ´readonly´ mode where D2X-XL will not try to write any data to disk (will slow down model and level loading). Enable by placing ´-readonly´ in d2x.ini
