These lumps must be compiled by various tools, and offer advanced control of some ZDoom aspects.

• ANIMATED Animations Boom Style.
• BEHAVIOR A compiled ACS script lump.
• GENMIDI Register values for MIDI instruments in OPL emulation.
• SNDCURVE Sound curve lookup tables, originating from Heretic and Hexen.
• SWITCHES Switch textures Boom Style.
• Libraries Libraries can be used to allow a certain set of ACS functions to be used on any map.
• DIALOGUE A built-in conversation system.
• TEXTURE1 and TEXTURE2 Doom's original texture definition lump.
• TITLEMAP A map which can be used as a replacement for the title screen.

These lumps are image files or ANSI colored text graphics.

• CONBACK Console background, if not supplied TITLEPIC is used instead.
• ENDOOM The special text screen displayed when quitting the game, if the option to display them is turned on.
• TITLEPIC Picture displayed on the title screen if no TITLEMAP is present.
• AUTOPAGE Optional background for the full-screen automap.

These lumps are used as markers between lumps to give them special identification or attributes. These are not needed when Using ZIPs as WAD replacement.

• HI_START / HI_END Used to define hi-res textures to replace textures already defined.
• TX_START / TX_END Used to identify the lump between them as textures/flats.
