The Doom + Doom II version published on August 8, 2024, added most notably two different Ogg Vorbis versions of the Doom and Doom II soundtracks, one being recording from an SC-55, the other being Andrew Hulshult's IDKFA remix. As a result, it is now significantly larger. It appeared in multiple versions, with the October 3, 2024 release adding a second TRAKINFO lump:
