Doom for the Atari Jaguar was published late in 1994. Though it was not the first console port released, it was the first one that began development and was the basis of most of the subsequent console ports of the time.
Doom for the PC was originally released in December 1993, only a few months after I got my first PC. I remember thinking when the console ports started showing up that it seemed like an older game by then though I think that was just because Doom II had already been released for the PC. While Doom and Doom II were not hugely different, there were enough minor improvements in Doom II to not bother with the original anymore.
The Jaguar version of Doom supported two-player cooperative or death match play using the Jaguar's proprietary JagLink network interface. It was one of only three games to support that device. There were differences between the PC and Jaguar version of Doom but for the most part they were relatively minor. The levels were slightly different and sometimes simplified and the number of textures used on any given level were reduced. There were also less textures per level in general and other minor changes. The biggest difference was probably that there was no music during gameplay. The reason for the lack of music was that the DSP normally used for music in the Jaguar was being used to support collisions detection and other things to improve the game quality instead.
Unfortunately to play the Jaguar version of Doom you'll have to track down an original copy or try your luck with emulation. There are no contemporary releases of that particular version. However, no version really ever bested the original PC version anyway. If you are going to play Doom then you might as well do it on a PC. However, if you have a Jaguar and want an easy way to play Doom then there is no reason not to grab this one. It's a great port overall.
