This guy has made a pretty faithful Wolf3d port to ZDoom, a DOOM source port engine. It's pretty easy to get going, and includes all six original episodes as well as the Spear of Destiny levels. Aside from being able to configure the game with ZDoom's options, the only differences I can spot are that the secret area walls raise up instead of push back, a la DOOM, and the lack of movement friction found in DOOM is there (the original Wolf3d had no friction and so the movement felt pretty different than this TC's). You can also play it with GZDoom, the OpenGL executable for ZDoom, and it looks pretty good, all things considered.
Considering there aren't any quality source ports of Wolf (and probably won't be), this is probably the best way to get a Wolf3d experience outside of emulation or resurrecting a Win98 machine or something.
