Mario takes the player slot in Doom
gzdoom-sm64 replaces the Doom player with Mario through libsm64. It is based on GZDoom 3.2.0, giving the crossover a specific engine baseline rather than following every feature of current GZDoom. The library brings Mario’s movement and rendering into the host; the Doom WAD still supplies the environment.
That combination is the reason to try it: familiar Doom spaces become a setting for a different character. It is not a package containing Doom and Super Mario 64, and it does not turn either original campaign into newly authored crossover levels.

Supply both games’ required files
Use the project’s release with a Doom WAD and your own US Super Mario 64 ROM, named sm64.us.z64. The listed development release directs ordinary users to release.7z rather than the source archive. Keep those game inputs separate from the source-build instructions.
The creator calls this a work in progress and says only that some Doom mods may work. Treat a favorite WAD or gameplay mod as a compatibility experiment, not as something guaranteed by its support in another GZDoom version.
