The '''[[Wikipedia:{{wp|Super Nintendo Entertainment System|Super Nintendo]]}}''' version of Doom was developed by [[wikipedia:{{wp|Sculptured Software|Sculptured Software, Inc.]] }} and was published by [[wikipedia:{{wp|WMS Industries|Williams Entertainment]] }} in North America and Europe, and published by [[wikipedia:{{wp|Imagineer_(Japanese_company)|Imagineer]] }} in Japan. It was released in September 1995, near the end of the system's life cycle. The cartridge features a [[wikipedia:{{wp|Super FX|Super FX 2]] }} chip, and was one of few SNES games to feature a colored cartridge, with the NTSC version being available in a red casing. The game does not use the [[Doom engine]], but features a custom engine programmed by Randy Linden.
== Details ==
SNES Doom features 22 levels from the PC version. The [[status bar]] is rearranged, though it keeps the concrete theme of the PC version, featuring an image of the weapon current held instead of the original numbers. Unique to this port, the floors and ceilings lack texture mapping. The game lacks any back-up or password system, meaning that each episode must be finished from the beginning. [[Multiplayer]] was available if the player bought an [[wikipedia:XBAND{{wp|XBAND]] }} modem. Due to memory limitations, the enemies only display from the front, causing them to appear to always face the player. Because of this and perhaps to conserve processing power, [[Monster infighting]] was not implemented, although it was made possible for monsters of the same type to damage each other with projectiles [[projectile]]s in this version of the game. Also as a likely means to conserve processing power, sound propagation is unused, rendering all enemies deaf. For whatever reason, circle-strafing [[circlestrafing]] is not possible, though standard [[strafing ]] is still functional. The game runs at the system's most commonly used resolution of 256 x 224, though it does not fill the entire screen; instead, it runs in a window surrounded by a black frame.
Interestingly, the maps used in the Super Nintendo port are derived from the PC version as opposed to the [[Atari Jaguar]] version, as every other port until the [[Xbox]] version used. This means that they are actually more intricate and detailed than their counterparts on the more powerful consoles, though they are still retextured to a degree as a result of reducing the pool of available textures. The [[Cyberdemoncyberdemon]] and [[Spiderdemonspiderdemon]] monsters that the [[Atari Jaguar]] and [[Sega 32X]] versions lack are also present. The musical score plays new arrangements of each track written for the [[wikipedia:{{wp|Nintendo S-SMP|SPC700]] }} sound coprocessor, rather than the PC version's [[MUS]] songs. Liberties taken include changing distorted guitars to orchestral strings in select tracks, and rearranging the levels on which some songs play. Like the [[3DO]] port, this version's music is generally considered to be of high quality.
It has a unique [[skill level|difficulty ]] system wherein later episodes can only be accessed on harder difficulties. However, this is subverted in the later Japanese release of the port, which restores full access to any episode from any skill level. [[Blood ]] on bullet impacts is removed, though given the lack of censorship in all other aspects of the content, as well as the lack of bullet puffs, it is likely that this was done for performance reasons rather than as any attempt to tone down the game's violence. Also for performance reasons, this port lacks transparent midtextures like its Jaguar counterpart.
The [[automap]] display takes advantage of the rotating and scaling of the Super FX chip, with the entire map spinning around the player's position rather than the player being portrayed with an arrow. Due to system limitations, no [[particles]] such as blood impacts, smoke or bullet sparks are present in the game - indeed, the [[shotgun]] does not fire seven individual shots as normal, but rather functions something like a slug gun or hunting rifle. This allows a player to shoot — and be shot — from a distance using the shotgun with no decrease in power. Moreover, the player's [[chaingun]] is now capable of single fire (although emptying one's bullet stock still produces a [[Chaingun makes two sounds firing single bullet|doubled sound effect]]). Finally, [[Nightmare]] mode does not feature [[Spawning#Monster respawning|respawning monsters]], but still contains very fast and tough monsters as normal.
==Other differences to the original version==
* Due to the absence of transparent midtextures, the level design does differ from the PC version in some areas, and compensation is handled inconsistently. In [[E1M1: Hangar (Doom)|Hangar]], the wall grates in the final room before the exit switch are simply absent, making this the only version of Doom allowing you and the monsters to move freely between those areas. In [[E1M3: Toxin Refinery (Doom)|Toxin Refinery]], the grates lining the parameter of the nukage pit in the beginning have been replaced with sector-based safety ramps, ala the Jaguar version. However, there is no replacement for the missing grates blocking the courtyard in the secret accessed via the yellow card, though it remains impassable.
* In the absence of [[E2M5: Command Center (Doom)|Command Center]], the secret exit for [[The Shores of Hell]] is now located in [[E2M3: Refinery (Doom)|Refinery]], behind the secret [[supercharge]] in the nukage near the exit, unlocked with an added switch. This new room contains three [[Ammo|energy cell packspack]]s, two [[AmmoBox of rockets|boxes of rockets]], one [[Cacodemoncacodemon]] on [[Skill_level|Ultra-Violence]] and higher, and two [[Imp|Impsimp]] s on [[Skill_level|Hurt Me Plenty]] and lower.* Rockets are much stronger, and are able to take out enemies such as the [[baron of hell ]] with only three shots versus the five to six in the PC version.
* The [[plasma gun]] is significantly stronger and uses fewer sprites in its firing sequence.
* It is possible for the player to collide with his own fired projectiles (such as rockets and plasma) if the projectiles are fired while the player is running.
* The [[BFG9000|BFG]] does not display an explosion graphic as it does in other versions; it simply fires a round that looks like a baron fireball and causes a ripple effect without the animation.
* All three of the aforementioned weapons utilize the imp/cacodemon/baron fireball launching sound effect when fired.
* In a rather humorous fashion, the Cyberdemoncyberdemon's rockets fire out backwards. This is an unfortunate side effect of the developers using single-angled sprites, seeming to forget that the player and Cyberdemon share this projectile.* Many sound effects have been simplified. They are sampled at a lower rate, and there is far more reuse than there is in the PC version. [[demonDemon|Pinky demons]] share the [[imp|Imp's]] pain and death sounds, and rocket and [[barrel ]] explosions share the generic fireball explosion sounds.* This is the only version of DOOM Doom to use cylindrical collision on actors. All other versions use rectangular bounding boxes, with fixed alignment no matter which [[angle ]] the actor is facing.
== Easter eggs ==
At the bottom of the [[Knee-Deep in the Dead]] [[sky ]] texture is a message reading, "Randy Linden ♥ Jodi Harvey." This [[Easter egg]] can only be seen if the player looks inside the ROM's graphical resources, or uses a [[Wikipedia:{{wp|Action Replay|Pro Action Replay]] }} code that allows walking through walls in areas where the sky is visible.
Within the ROM itself, a hidden message can be found which reads, "NRage / Reality Engine written by Randy Linden. Special thanks to my loving wife, Jodi Harvey." It can only be found if the ROM file is opened in a hex editor, and is found at position 10E (270 in decimal).
