Doom 64: 4 Open Source Clones Compared
Doom 64 EX+ is a community continuation of the original Doom64EX project: it requires the IWAD from Nightdive Studios' 2020 official remaster instead of the older ROM-dump-derived data files Doom64EX still uses, replaces Doom64EX's FluidSynth audio with FMOD Studio, adds PWAD support for custom maps, and extends the map-slot limit past MAP40. Doom 64 for Dreamcast is a separate, Dreamcast-exclusive project built on a different lineage -- Immorpher's Merciless Edition and Doom 64 XE, themselves based on the DOOM64-RE reverse-engineering effort -- and can use either an original N64 ROM or that same 2020 remaster IWAD. doom64DS is an older, halted DS port with no further documented details.
