A modder known as RPGKing117 has created mods that allow players to run The Elder Scrolls III: Morrowind and Fallout 1 within Fallout 4. The mods utilize Fallout 4's Pip-Boy and computer terminals for gameplay. A demonstration of the Morrowind mod is available on YouTube, showcasing it running on a computer terminal.
The Morrowind mod streams the game's framebuffer into the Fallout 4 Pip-Boy display in real time. It uses a custom fork of OpenMW, which is included with RPGKing117's installer on GitHub. The OpenMW build runs in a hidden window, upscaled to 1024x1024, and streams its framebuffer directly into the Pip-Boy display. A custom F4SE plugin handles the holotape trigger, the shared-memory bridge, and input passthrough.
To run the Morrowind mod, players need Steam copies of Fallout 4 and Morrowind, along with the Fallout 4 Script Extender. The modder is also working on polishing the original Fallout version for release. Most OpenMW-compatible mods should work, according to the modder.
