PlayStation Doom: Master Edition

PlayStation Doom: Master Edition is a hack created by Team GEC and a team of about a dozen mappers (CoTeCiO, Dark Pulse, DeXiaZ, Dragonsbretheren, DynamiteKaitorn, Impboy4, marver0PS, mr-around, riderr3, Saint_Guy, and Uroboros87) from the Doomworld community, aiming to backport all cut Ultimate Doom, Doom II, Final Doom, and Master Levels maps, as well as add in No Rest for the Living, Xbox Doom's added maps, custom maps by John Romero, and Tom Mustaine's Doom2 Map14 Homage into PlayStation Doom and Final Doom.

Unlike the PlayStation Doom TC, this modification creates a hacked and modified version of the original game, and runs on the actual PlayStation hardware (along with s). The ultimate aim is to have versions of all official maps, along with some custom maps by notable creators, given the PlayStation Doom treatment, while remaining as faithful as possible given various technical limitations and omissions of PlayStation Doom (for example, no arch-viles, as the monster does not exist in PlayStation Doom/Final Doom).

Upon loading the hack, after a few introductory FMVs, the player is presented with a new menu which allows for the player to select a set of levels to load. As of Beta 3, these selections are as follows:
 * Doom: contains (Ultimate) Doom, Doom II, No Rest for the Living, SIGIL, Romero's other maps, and the Xbox maps
 * Master: contains the Master Levels, as well as various custom PWADs from Master Level authors, such as Sverre Kvernmo's Cabal series, Dr. Sleep's Crossing Acheron, etc.
 * TNT: contains TNT: Evilution
 * Plutonia: contains The Plutonia Experiment

The chosen set of levels is then loaded. Everything besides the original Doom episode uses the PlayStation Final Doom engine; the original Doom episode uses the original PlayStation Doom engine (and its reduced limits).

The hack also contains some quality-of-life improvements; for example, restoring a Nightmare! difficulty which is similar to the PC version (except for a lack of respawning monsters), re-enabling a VRAM Viewer cheat code, and some bugfixes related to switches and texture animations.

The current version, as of October 1, 2019, is Beta 3, released on the same day.

Betas 1 and 2 contained a level, "New Hangar" by Team GEC, which was removed in future releases. It served as a testing playground for hacking the games.

Cheat codes: PlayStation Doom has an unused cheat code that enables a "VRAM Viewer", which the Williams team used to test the positions of textures and flats loaded in the VRAM when converting maps, and was disabled for the release of the game. In the Master Edition version, this code is reactivated.
