The game's port was done in three weeks by id Software themselves, being contracted by Japanese software developer and publisher Imagineer, paying id Software $100,000 in advance to do so. While the company original sought Rebecca Heineman to do the SNES port, she was unable to program the game in the allotted time, forcing the id Software team to port their own game over in the aforementioned tight deadline.

In the game, you play as William "B.J." Blazkowicz. The storyline of the game has been slightly altered from the original; instead of being a P.O.W. in Castle Wolfenstein, you are sent to several different castles to take out Staatmeister's evil thugs and thwart his plans. In the Japanese version, his name was changed to Colonel Trautman, and you must defeat all of his mutants, which include all the guards.

While the game is a port of the original Wolfenstein 3D, it uses many elements from its later release, Spear of Destiny (DOS) including bosses, graphics, and even music.

The SNES version of the game spread a lot of controversy because of its censoring of blood, Nazis and Nazi symbols, replacing dogs with rats and Hitler with Staatmeister (Country Master) who is basically a rehashed version of Hitler without a mustache. The guards and bosses no longer speak German and instead say "Halt!" and "Coming for ya!", respectively. The game also has no save feature, and instead features a password system for each level for each of the three levels of difficulty. However, one feature the SNES version has over the DOS original (besides the better quality music) is an automap feature. However, unlike DOOM, items aren't shown on the map; only the walls, and can only be accessed when the game is paused, not while the player is playing a level.

The SNES port of Wolfenstein 3D uses music from Wolfenstein 3D (DOS) and Spear of Destiny (DOS), but the quality of the music is slightly improved thanks to the more advanced audio chip of the SNES. It sounds particularly better with the percussion instruments, but unfortunately, the port doesn't take full advantage of the audio capabilities of the SNES chip, so the sound is only marginally better.

Though Bobby Prince could not really remember much about the SNES version due to the passing years, John Romero gave us verification that Prince arranged his own music. Though it has an identical sound to the DOS originals, some things were changed, such as instrument designs being changed, some of the drum beats have been either slightly or completely altered, and even some instruments missing from the DOS originals completely. Another thing to note is the tempo of the SNES version's music is faster than the DOS originals. Prince used Sequencer Plus Gold and his Ensoniq EPS to compose the original soundtrack, and he most likely arranged the SNES version's MIDI files in the same program with the same keyboard. These MIDIs were then converted into a sound driver by Rebecca Heineman, who goes uncredited.
