Sega Saturn
From Doom Wiki
The Saturn version of Doom was published by GT Interactive in 1997. This version was a port of the PlayStation version and was developed by Rage Software. It features both Doom and Doom II with the extra levels and sound design of the Playstation version.
It was widely noted for being a rushed port with a very choppy frame rate and lacked several features from the PlayStation version. The Deathmatch and Cooperative multiplayer modes were no longer present. This version removed all of the colored lighting effects as well. In addition, the animated fire sky that was featured in some levels was replaced with the cityscape that was featured in levels 10-20 of the PC version.
The information on the back of the box also contained numerous errors. Both the European and North American versions had screenshots that were taken from the PC version of Final Doom. In addition, the North American version listed that the game supported 2 players via linkup; this was not true, the game only supported single player.
[edit] The Japanese version
The Saturn version was published by Midway in 1997. This version was a port of the PlayStation version and was developed by Softbank Corp.
This port was similar to the North American and European versions with a few differences. The most important difference was that this version sported a much smoother frame rate, staying around 25 to 30 frames per second. [citation needed] This version does contain a cooperative and deathmatch mode via link cable that is fully functional. The game disc also serves as a soundtrack when inserted into a CD player.
