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 [http://deathz0r.slipgate.org/alpha.php here] (Note that they are still development/education quality, being straight ports of the maps, and not meant for use as a typical game addon).

Revision as of 12:25, 18 October 2019

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

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 (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

v1.0

  • Released December 10, 1993.
  • 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

  • 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.
  • The "This version is NOT SHAREWARE, do not distribute!" text was added, to be shown with the registered version.
  • Many more, including capitalization, spelling corrections and additional error messages.

v1.2

  • Released February 17, 1994.
  • Rewritten sound code.
  • Modem/null-modem support. This release saw the network code split into external "drivers", providing a modular network system.
  • PAS-16 stereo support.
  • First appearance of "Nightmare!" skill level.
  • Mouse and joystick can be used in the menus.
  • Gamma correction mode was expanded to include five settings (0–4).
  • Improved joystick calibration.
  • Multiplayer text macros.
  • The -left and -right network options no longer work.
  • Textual changes:
    • "CENTER the joystick and press button 1:" was added, changes to other joystick messages were also made.
    • "I_StartupSound: forking sound daemon." in 1.1 was changed to "I_StartupSound: Hope you hear a pop."
    • "OpenSocket: ..", "ListenForPacket: .." and a few others were removed.
  • The status bar is modified and now uses a single STBAR image as a backdrop.

Bug fixes:

  • Fix for the broadcast packet bug which caused many networks to suffer decreases in performance.
  • 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

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

  • Improvements to MIDI and modem code.
  • Additional PAS console information.
  • Could load doomr.wad (commercial mode, what would become DOOM2.WAD).
  • 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 1 unique executable, "regdev" would have meant "registered development mode" and the "com" in "comdev" would have meant "commercial".

Ultimate Doom

Final Doom

  • 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 doesn't 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

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 missing yellow key in TNT MAP31 was fixed.
  • Missing deathmatch starts in both TNT: Evilution and The Plutonia Experiment were added.
