Modder RPGKing117 has had a busy month: He committed the blasphemy of putting Skyrim quest markers in Morrowind, achieved the triumph of cramming Morrowind into Fallout 4, and has no come back for one last job: Making Fallout 1 playable on Fallout 4’s Pip-Boys and assorted vacuum tube, monochrome computer terminals.

This sequel mod does not yet have a public release, but will presumably be made available on RPGKing117’s GitHub and Nexus pages like the Morrowind project before it. We do, however, already have a YouTube video of the mod in action for our viewing pleasure.

The Morrowind Mod used Fallout 4 Script Extender and the OpenMW source port to run both games at the same time, rendering Morrowind on the in-game screens of Fallout 4. Script Extender allows the player to launch Morrowind from within Fallout 4 and pass your control inputs through both games. A custom version of OpenMW streams its framebuffer⁠—the data sent from your GPU to your screen⁠—onto the in-game screens of Fallout 4.

As for how the Fallout 1 mod differs from the Morrowind one, we won’t know the full story until RPGKing117 releases the full project on GitHub. There’s a source port like OpenMW available for Fallout 1, Alex Batalov’s Community Edition, and my assumption would be that this is what RPGKing117 used in his own project.

If you want to try this mod for yourself, keep an eye on RPGKing117’s Nexus Mods or GitHub page for its release. I’m a huge sucker for game-within-a-game gags like this, and I’m always keen to see the farthest frontiers of absurdity people are willing to reach. Plus, much as I love the “Doom on anything” gag, it’s nice to see people branch out into other classics.
