Editing Sega 32X

[[Image:32X_Doom_Box_Art.jpg|thumb|Box art for the U.S. 32X version of [[Doom]]]]
The '''{{wp|Sega 32X}}''' version of [[Doom]] was developed directly by [[John Carmack]] and was published as a launch title for the {{wp|Sega Genesis}} add-on peripheral by {{wp|Sega}} in {{timeline|1994|November 1994}}.

The game features seventeen maps from the PC version's first two episodes. It disappointed many fans since it does not play in full screen, is missing many maps and several monsters, only displays front-facing rotations for sprites, is missing many sound effects, has no save feature, and has extremely poor music. Much of this is blamed on a rush to get the game out in time for the 32X launch date, while other aspects are simply due to the fundamental limitations of the console.

It is based on and builds from the same source code as the [[Atari Jaguar]] version, using a conditional {{c|MARS}} define to distinguish between the two platforms. "MARS" was the development codename for the 32X system.

== Features and limitations ==
Only front rotation frames are provided for sprites such as monsters and rockets. Because of this, there is no [[monster infighting]] in this version. Likewise, as in the Jaguar and [[Super Nintendo]] versions, [[Strafing|circlestrafing]] is not possible due to the use of a "strafe on" key which overrides the ability to simultaneously turn, rather than separate left and right strafe keys.

As with the Jaguar version, the maps have been edited significantly to cut down the amount of geometry and texture usage, and the game does not feature the [[cyberdemon]], [[spiderdemon]] or [[spectre]]. Due to a complete lack of levels from the [[Inferno|third episode]], it also lacks the [[BFG9000]] during normal play. However, it is still documented in the game's manual, and the number "7" still exists on the status bar. A cheat code can give the weapon to the player, showing that it was coded in even though it does not appear in any of the maps. This version also has no [[multiplayer]] mode.

There is no way to save games, although there is a level select option that allows the player to start on any of the first fifteen maps.

Due to poor use of the {{wp|Yamaha YM2612|YM2612 FM synthesis chip}} in the Genesis, this version's soundtrack is noticeably inferior to that of other versions, particularly the contemporary Super Nintendo and [[3DO]] ports. The low-quality, noisy FM instruments have often been compared to the sound of flatulence.{{cite web|author=Hart, Aimee|title=Doom 32x Soundtrack Has Been Compared to Farts and Now We Can’t Hear Any Different|url=https://www.gamerevolution.com/news/409985-doom-32x-soundtrack-has-been-compared-to-farts-and-now-we-cant-hear-any-different|publication=GameRevolution|publishdate=23 July 2018|accessdate=1 June 2023}}

If the player cheats while playing or uses the level select option, they will not see the real ending to the game and will instead be presented with a DOS prompt (C:&gt;) after completing MAP15. The game manual incorrectly states that the game will then warp the player back to MAP01 to try again without cheats; however, this does not happen.

== Technical details ==
[[File:32X_Doom.png|thumb|right|A screenshot from the 32X version of Doom.]]
The Sega 32X version of the Doom IWAD uses the same [[wall texture]] format as the Atari Jaguar port: the "patches" are in a headerless, row-major, raw format, with the first 320 pixels repeated at the end. The TEXTURE1 lump contains dimension information for each texture, which are otherwise ambiguous (for example, both DOORBLU and CRATINY are 1344 bytes in size, but one is 8x128 pixels, while the other is 64x16 pixels).

The [[palette]] is stored in a lump named PLAYPALS instead of PLAYPAL. It contains a total of 15 palettes, instead of 14. The first 14 are unmodified, the last one is a palette with a blue tint. The COLORMAP lump contains 64 light levels, instead of 32+2.

Audio data and UI graphics (font characters, [[status bar]], [[title screen]] pictures, and so on) are not found in the IWAD, but are instead stored within the cartridge ROM in proprietary Genesis hardware formats.

== Map list ==
The map list consists of the first two episodes of Doom, minus the Tower of Babel (the [[cyberdemon]], like the [[spiderdemon]], is not included in the game). Most of the levels have been retextured and simplified to require less resources; many of the [[The Shores of Hell|Deimos levels]] have even undergone severe cuts compared to the PC originals. Curiously, the final and secret levels are numbered 23 and 24, leaving a seven-level gap in the enumeration, which might have been originally intended for the seven levels of [[Inferno]] that do not contain monsters absent from this port (E3M1 to E3M7, leaving E3M8 and E3M9 out, like the Jaguar version of the game).

== Bugs ==
* It is impossible for the player to select [[fist]] when they have a [[chainsaw]], even when they are powered with [[berserk]] pack. After picking up a berserk pack the players should predict a situation when a more powerful weapon than a powered fist is needed or find another berserk pack in the level (as in [[MAP12: Deimos Lab (Console Doom)|MAP12: Deimos Lab]]).
* Some [[status bar face]] graphics are flipped left to right with respect to the originals, so that when the [[Doomguy]] takes [[damage]], the part in his hair appears to jump from side to side.

I spent weeks working with Id Software’s John Carmack, who literally camped out at the Sega of America building in Redwood City trying to get Doom ported. That guy worked his ass off and he still had to cut a third of the levels to get it done in time.<br/><br/>What amazes me now is that with all that going on, nobody at Sega was willing to say "Wait a minute, what are we doing? Why don’t we just stop?" Sega should have killed the 32X in the spring of 1994, but we didn’t. We stormed the hill, and when we got to the top we realized it was the wrong damn hill.|
