Jag Doom

A screenshot from the Jaguar version of Doom.

Atari Jaguar gamepad overlay for Doom.

The Jaguar version of Doom was published by Atari and was developed by id Software. It was released on November 28, 1994.

Like the PC version, this version of Doom was developed on the NEXTSTEP platform, and compiled to run on the Jaguar. The bulk of the engine was programmed by John Carmack, while Dave Taylor handled the multiplayer code.

This version was the first official port of Doom to begin its development cycle, although the 32X version was released first. The 32X, 3DO, GBA and PlayStation ports are all derived from this port.

There was a television commercial for this port which interspersed gameplay screens with a priest letting loose incendiary rants.

Differences between the Jaguar and PC versions[]

This version of Doom only features one continuous "episode" like Doom II, as opposed to the three episodes in the PC version. Unlike Doom II, there are no text intermissions to separate the game into segments, although the sky does change after MAP08 and MAP19. 22 of the 27 maps from the PC version are featured, although all have been modified, some significantly, along with two new maps. The missing maps are Tower of Babel, Hell Keep, Slough of Despair, Dis and Warrens. To add a slight bit of confusion, the two new maps take the names Tower of Babel and Hell Keep, while Fortress of Mystery has been renamed Dis in this version.

As mentioned above, the maps are modified from their originals. They typically use less texture variation and have simpler geometry versus their PC counterparts. For some of the larger maps, entire portions of their layout have been removed. In addition, crushers are no longer present in any of the maps. Despite using fewer textures, many maps now have entirely new texture themes, and several new textures have been added. Some of these textures are taken from Doom II, but others are new to this version.

The cyberdemon and spiderdemon monsters are not present. Spectres are still included in many maps but are rendered normally, without the partial invisibility effect, which makes them indistinguishable from demons. The partial invisibility and light amplification visor items have been removed from any maps that originally featured them. Interestingly, MAP24 still has a partial invisibility thing, but it is flagged to only appear in multiplayer and that map is not available from the area selection menu. Health and armor bonuses now give two points instead of one, but about half of them are removed from the maps.

For the skill levels, I'm too young to die was renamed I'm A Wimp, and Hey, not too rough was shortened to Not too rough. Also, Nightmare mode in this version is similar to UV -fast, as enemies no longer respawn like on Nightmare mode in the PC version; here they only have their -fast parameters.

The Jaguar version is the only console port that does not feature any music during gameplay. This is because Jaguar's mathematics co-processor DSP chip also handles playing music. As Doom uses the DSP for most of the collision detection and other things, the DSP does not have enough free cycles to process music while running the other game functions. The port does, however, have music for the title and intermission screens. Possibly due to lack of music in the maps, the intermission screens feature renditions of selected tracks from the PC version soundtrack instead of a dedicated intermission track.

In addition the pitch of noises are slightly lower than in the PC version, probably again stemming from the DSP chip in the Jaguar.

Given the Atari Jaguar controller's large number of buttons, this version is the only console port with direct access to all weapons, instead of cycling through as in other console versions. As a bit of a trade-off, this version does not have dedicated strafe buttons, instead C must be held along with a direction.

This version has a 2 player mode for cooperative play and deathmatch via JagLink, a proprietary network interface that was separately released for the console.

The status bar has been redrawn. It is now brown, larger and rearranged compared to the PC bar, and no longer features the ammo totals panel. Instead, an area counter panel now shows the number of the map you are playing. When playing multiplayer the arms and area panels are replaced by your frags and his frags panels, his frags showing your opponent's number of frags.

This version does not allow saving during maps, but will remember any map completed. The player can choose to start on any map that has been completed from the main menu.

Bugs[]

General[]

The file in_main.c of the source for this version contains definitions for two more maps, Fortress of Mystery and Warrens, which are commented out. Seemingly both maps were planned to be included. A hint for this can be found by using the level warp cheat. This cheat uses the numbers on the gamepad, and they work for all 24 maps. If one tries this for MAP25 or 26, the game crashes with an error message. This does not happen if one tries it with numbers 27 and up.

Map-Specific[]

MAP02[]

An Imp is placed outside of the map boundary behind the exit switch, making it necessary to shot the wall behind the switch with the rocket launcher to kill the Imp to get 100% kills.

MAP10[]

The secret area that branched off the crusher hallway in the PC version is still present in the map, but only accessible using a glitch.
