Overview
- Modder RPGKing117 released the playable crossover with a GitHub installer that bundles a custom OpenMW fork and posted a YouTube demo showing it running in-game.
- OpenMW runs in a hidden 876x700 window upscaled to 1024x1024 and streams its framebuffer to the Pip-Boy, with a custom F4SE plugin handling the holotape trigger, shared memory, and input passthrough.
- The mod requires Steam versions of Fallout 4 and Morrowind plus the Fallout 4 Script Extender, and it needs a 64-bit Windows 10 or 11 PC with enough power to run both games at once.
- PC Gamer notes the setup may struggle on lower-power devices like the Steam Deck, and reporters frame it as a clever proof of concept rather than an ideal way to play a full Morrowind run.
- The Nexus Mods upload is quarantined over custom DLLs, so the download is currently available only on GitHub, and the author says a separate Fallout 1 version will release after more polish.
