Guide: Running Doom 64 CE in RetroDECK

Doomce logo

Doom 64 CE is a set of overhauled total conversions for GZDoom, recreating PlayStation DOOM and DOOM 64 with modern engine features.

Building on PSX DOOM TC and DOOM 64 Retribution, it updates the originals to leverage recent GZDoom capabilities and adds features previously unavailable.

Highly modular, Doom 64 CE allows players to choose a near-vanilla experience or enable enhancements like upscaled textures, PBR materials, and advanced particle effects.
