Contains the base PSX DOOM CE, PSX FINAL DOOM CE and DOOM 64 CE mods without any addons. Requires DOOM2.WAD and a patched DOOM64.IWAD (see prerequisites instructions below). Comes bundled with GZDoom 4.8.2 for convenience, but you can use an existing installation of it. Read the readme for more details.
NOTE IF UPGRADING FROM VERSIONS EARLIER THAN 3.0.0: It is necessary to delete DOOM64.IWAD and DOOM64.CE.LostLevels.pk3 and run the installer again. Any map packs from ModDB's addon section will also need to be redownloaded to use their latest version. After upgrading, it is safe to delete the file named (...).Base.pk3, because it is no longer used in this version.
Starting from version 2.0.5, PSX DOOM CE does not run standalone and requires the DOOM 2: Hell on Earth WAD (DOOM2.WAD) to run. This change was made because many of the map packs being ported depend on DOOM 2 assets that are not present in PSX DOOM.
The BFG Edition and Unity rerelease DOOM 2 WADs are not supported. If you have DOOM 2 installed in Steam, open its installation folder and copy DOOM2.WAD from the base folder (not rerelease) into your gzdoom directory.
If the wad is present, you will be able to select PSX DOOM CE from the list when opening gzdoom.
Starting from version 2.0.4, DOOM 64 CE does not run standalone and requires a copy of DOOM 64 for Steam or GOG to work. The Steam DOOM 64 IWAD (DOOM64.WAD) can't be used as is and requires patching to make it discoverable by gzdoom. An automatic patcher is included in this package to make this process easier:
Run doom64-install.bat. It will try to find your Steam installation of DOOM 64 and automatically patch and create all necessary files to play. If for any reason the Steam installation is not found, you can copy DOOM64.WAD to the same folder as the .bat file and it will use that instead (special thanks to phredreeke for the idea and initial implementation).
Once it finishes, open gzdoom.exe and you will be able to select DOOM 64 CE from the list. If you do not wish to use the bundled gzdoom and have it installed elsewhere, copy the IWAD and PK3s to its location or the paths configured in its [IWADSearch.Directories] and [FileSearch.Directories].
