Difference between revisions of "Versions of Doom and Doom II"

Latest revision as of 06:53, 9 February 2024

From 1993 to 1995, various versions of Doom and Doom II were released by id Software to address bugs and input from players and fans. Additionally a few pre-release builds were preserved by testers, which eventually made their way to public archives. Summarised below are the main differences of each known version of the games, as changes were made. Executable and IWAD resource differences are noted, as well as what levels were modified, if any. For details on what was changed in each level, refer to the article about that level.

Pre-release builds[edit]

In order to make playability of these pre-releases easier a batch launcher has been provided below (Must be run in DOS/DOSBox). Alternatively a map pack WAD with all the pre-release levels is available here^{[dead link]} (Note that they are still development/education quality, being straight ports of the maps, and not meant for use as a typical game addon).

Release builds[edit]

v1.0[edit]

• Initial public release.
• Internally numbered as v0.99.
• No registered version yet.
• It is possible to play the 1.1 registered IWAD with this version, one must rename this WAD to "doom1.wad", it also mentions that this is the "commercial version" in the startup screen, rather than registered.

v1.1[edit]

• Released December 16, 1993.
• The first registered release of Doom.
• First appearance of gamma correction, which is either on or off.
• A more stable version of the DOS extender (DOS/4GW).
• Sound Blaster 1.0 support.
• Textual changes:

• At the text screen of Knee-Deep in the Dead "buy" is changed to "play" in the final sentence.

• Many more, including capitalization, spelling corrections and additional error messages.

• Serial mode multiplayer was added.
• The command line parameters -send and -receive were added.

v1.2[edit]

• Released February 17, 1994.

  • "OpenSocket: ..", "ListenForPacket: .." and a few others were removed.
• The status bar is modified and now uses a single STBAR image as a backdrop.
• A change in the way teleports work makes telefrags possible.

Bug fixes:

• Runs under Windows.
• Z_Malloc error implemented.
• IRQ 2 works.
• Savegame slots 5 and 6 work.
• Switches and platforms work when reloading from a saved game.
• Network play no longer locks up when using a sound card.

v1.3[edit]

There are three known variants of this version: first level and second level betas, and a shareware build marked as v1.25. id Software stated that these beta releases were unauthorized, possibly because these executables had partial support for Doom II, which was being developed at the time.

Second level[edit]

• Improvements to MIDI and modem code.
• Additional PAS console information.
• Could load doomr.wad (commercial mode, what would become DOOM2.WAD).
• Skies are properly scaled depending on the screen size. This change broke sky rendering in low detail mode.
• Textual changes:

• "malloc() in I_InitNetwork() failed" was added.
• "program loaded at: 0x%p" was removed.
• "Game mode indeterminate" was added and "Adding external file %s." was removed.
• "registered version." was added.
• "Do not distribute!" was added when in commercial mode.

• -wart parameter was changed to support loading from MAP** files, also located in m:/cdata/ (including E*M* files).
• The command line parameters: -regdev and -comdev were added.

• -regdev loads these files: c:/localid/doom.wad, m:/data/texture1.lmp, m:/data/texture2.lmp, m:/data/pnames.lmp, and c:/localid/default.cfg.
• -comdev loads these files: c:/localid/doomr.wad, m:/cdata/texture1.lmp and m:/cdata/pnames.lmp.
• It is understood that these parameters were used to aid in the development of Doom and Doom II into one unique executable, "regdev" would have meant "registered development mode" and the "com" in "comdev" would have meant "commercial".

v1.25[edit]

Doom shareware v1.25 disks

A v1.25 build of shareware Doom was prepared by id Software for distribution by Sybex with the licensed book The Official Doom Survivor's Strategies & Secrets by author Jonathan Mendoza, which included two 3.5" high density floppy disks.

• Sound problem fixes.

v1.5[edit]

• Released August 3, 1994.
• ENDOOM had changed, text was added by Eric, calling himself a "DOOM-GOD" and John Romero a "Chicken", a reference of the former also appears on a newsgroup thread.^[3]
• All demos are different, but are recreations of earlier demos. DEMO1 is almost the same. DEMO2 is a cooperative demo, with some intentional frags, long rumored to be Leung and Romero playing. DEMO3 is another recreation.

v1.666[edit]

This version number is a reference to the number of the beast.

Doom II version[edit]

• Compiled August 30, 1994.^[4]
• Released September 30, 1994.
• An alternate version, dated August 25, 1994 is considered to be pirated.
• Addition of the -timer command line option.
• Doom FAQ updated to version 5.8.

Doom version[edit]

• Released September 1, 1994.
• OPL music playback crash was fixed.
• First appearance of -statcopy.

v1.7[edit]

• Released October 11, 1994.

• Sound code changes.
• Re-appearance of DeathManager! version 1.1.
• ENDOOM lump had a phone number change.

v1.8[edit]

• Released January 23, 1995.
• Doom FAQ updated to version 6.666.

v1.9[edit]

• Released February 1, 1995.
• A large amount of text from README.TXT was cut, presumably because it duplicated information that was already covered in the bundled copy of the Doom FAQ.

Ultimate Doom[edit]

• The engine internal version is still 1.9.
• Support for Ultimate Doom: can select the fourth episode, the ending text.
• Only the bosses present in original maps can trigger tag 666.
• The lost souls bounce off ceilings and floors (see Demo desyncing caused by bouncing lost souls).
• The executable expects four demos, and will exit after the third demo if DEMO4 lump is not present.
• Introduces a bug that would hide par times after idclev which affects Doom II and Final Doom.

Final Doom[edit]

• The engine internal version is still 1.9. The same executable is used for both the TNT: Evilution and The Plutonia Experiment; the game setting is selected depending on the IWAD name (either tnt.wad or plutonia.wad).
• New level names and intermission texts if playing Evilution or Plutonia.
• Teleporters do not set the Z coordinate, causing player to teleport into the air sometimes.
• Setting joyb_speed to 31 in the configuration file does not make the player always run as in the previous 1.9 versions, though the value of 29 works in all versions.

Final Doom, id Anthology version[edit]

Some copies of the id Anthology contain an updated Final Doom; the rest use the version described above. The GOG.com release uses this alternate version.

• The engine internal version is still 1.9, and likewise the same executable is used for both IWADs.
• The teleportation bug introduced in the original Final Doom was fixed.
• The bug with skies never changing was fixed.
• The missing yellow key in TNT MAP31 was fixed.
• Missing deathmatch starts in both TNT: Evilution and The Plutonia Experiment were added.
• Executable expects 3 demos again to resolve issues with IWADs other than Ultimate Doom. As a result, Ultimate Doom will only show the first 3 demos and it will not crash on IWADs where the fourth demo is missing.

Other[edit]

Source release[edit]

• The engine internal version is 1.10.
• This was a source release only. No binaries were included. The source code was for the Linux version, not the DOS one.
• The bug with skies never changing was fixed.
• The FixedDiv function uses floating-point division internally, leading to occasional desyncs.

Doom Classic[edit]

Doom Classic is a version of the Doom engine integrated into id Tech 4, originally created by Vicarious Visions for the Xbox ports of Doom and Doom II, and later carried across by Nerve Software for the Xbox 360 Live Arcade ports. It was ported back to the PC for Doom 3: BFG Edition.

• The internal version is 1.11.
• Code ported to C++ language.
• Thy Flesh Consumed levels have gained par times.
• Visplane limit raised to 384.
• Drawsegs limit raised to 1280.
• Built-in support for No Rest for the Living and the Master Levels.
• The renderer still works in 320x200, but this output is then scaled to 960x600.
• Maximum view bobbing amplitude reduced by 25%.

Doom Classic (Unity)[edit]

Further versions of the Doom Classic codebase have been developed as of 2019, utilizing the Unity game engine as an abstraction layer in place of id Tech 4. Development was initially handled by Nerve Software and then continued in-house at id Software.
