PC

Although adaptations of Doom 64 to other Doom engines existed prior, Doom 64 EX was the first engine to use partially reverse-engineered Doom 64 code. It natively supported the Doom 64 map format, which allowed the game to be played with decent accuracy. This has been used as a base for other PC engines including the official Doom 64 Remaster and modern console ports.

All Doom 64 PC engines allow for custom mod loading. The guide below describes how to load custom mods.
