DOOM

Batocera is shipped with the SHAREWARE version of Doom. So you can play Episode 1 of this insane 3rd person shooter from 1993.

When adding .wad files, make sure you put the filenames in lowercase. Uppercase .WAD won't work.

On some ARM platforms floor and ceilings got some disturbtive graphics output. Disabling it completely gets rid of the effect. This screenshot illustrates the problem at full effect! This is due to some fix for texture “vibrations” (not exactly the same issue as the wiggle but triggered with the same option) the fix was backported from prboom-plus but it seems it's causing trouble in some platforms.

So how to fix? Start PRBOOM → Options → General → 3rd page Whiggle fix → No

Annother method? Yes, navigate to /userdata/saves/prboom/[DOOM-EPISODE]/prboom.cfg and search Video Section for r_wiggle_fix and disable it.

SIGIL is the 5th Episode for ULTIMATE DOOM. It was created by the creator of DOOM - John Romero and can be downloaded for free right here.

How to use?

Place the downloaded WAD to your prboom directory in roms. Now edit /userdata/saves/prboom/[DOOM1-EPISODE]/prboom.cfg and set the WAD next to be loaded to the main WAD in Files Section. I've only tested for ULTIMATE DOOM and it worked like a charme.

The Lost Episodes of Doom is a collection of three eight-level episodes for Doom by Christen Klie and Bob Carter. It takes place on the Jovian moons Callisto and Io, and on Jupiter itself. It was a commercial product.

Extract the two WAD files and then edit /userdata/saves/prboom/[DOOM1-EPISODE]/prboom.cfg and set the WAD next to be loaded to the main WAD in Files Section.

No Rest for the Living was developed by Nerve Software for the release of Doom 2 on the XBLA. The episode consists of nine levels in all, eight standard levels and a single secret level, as a homage to the similarly structured nine-map episodes in the original Doom, particularly Knee-Deep in the Dead.

Extract the WAD file and then edit /userdata/saves/prboom/[DOOM2-EPISODE]/prboom.cfg and set the WAD next to be loaded to the main WAD in Files Section.

The above methods gots the disadvantage that you “lose” your original gameset. That means for DOOM-Sigil that you will the new launching screen ever and ever again. To get rid of this you can copy the main WAD and rename one to DOOM - Ultimate DOOM.wad and the other to DOOM - Sigil of Baphomet.wad now you edit /userdata/saves/prboom/DOOM - Sigil of Baphomet.wad/prboom.cfg and set it up like written above.

Now you edit gamedata and hide the added PWAD files (Sigil.wad), you now have a clean list.

If you intend to use Doom mods, you need to create subdirectories for each mod you want to enable, and keep a copy of the original doom.wad or doom2.wad in the mod subdirectory, with the corresponding .wad for the mod. Generally when you launch a mod, the Doom Logo has been modified by the modder and you can tell what is the base wad.

For example : Simpsons Ultimate Doom

In the screenshot below, you can see how you can make it work. The original .wad files have been renamed .wadd so that PrBoom doesn't load and give them priority over the other wads.
