Engines

The Doom 64 engine built upon the PlayStation Doom engine which itself was derived from the Atari Jaguar Doom engine. It utilized the Nintendo 64's 3D acceleration capabilities, thus it is a hardware-rendered version of the engine. The Doom 64 source code has never been officially released, thus various engines based on reverse engineering and adaptations to other engines have been made. Linked below is a list keeping track of many of them.

Given Doom 64's unique aesthetics, it has inspired many gameplay mods to give classic Doom its style. The following list links many such mods.

Although the source code for Doom 64 was never released publicly, the community would eventually completely reverse engineer the game. With the exception of the official Doom 64 Remaster, all of the Doom 64 engines which natively support its level format are open-sourced and are able to be modified.

PC Engines

Although adaptations of Doom 64 to other Doom engines existed prior, Doom 64 EX was the first engine support 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. The page below lists many of the PC engines that support the native Doom 64 map format.

Nintendo 64 Engines

The Doom 64 source code was not fully reverse-engineered until 2020, when Doom 64 RE was released. This release allowed Doom 64 mods to be made for Nintendo 64 hardware (and emulators). By updating the source code of these engines, you can create Nintendo 64 hardware compatible mods and games. The page below lists many of the Nintendo 64 engines and how to compile them.
