1oom-fork

About

Master of Orion is a 1993 turn-based 4X strategy game by Simtex, published by MicroProse, where players lead a spacefaring empire through exploration, diplomacy, and war against rival species. 1oom-fork reconstructs the original 1993 DOS release of Master of Orion so it runs on modern systems, aiming for accurate reproduction rather than a reinterpretation. It ships several interchangeable executables — a classic 1993-style UI, a text/command-line interface, and tools for viewing and editing the game's LBX data files. Notably, the README states this particular fork is no longer under active development and points players to a 'vanilla' continuation (1oom v2.0) for ongoing updates, even though the repository still shows recent commit activity.

Getting started

Requires a legally owned copy of Master of Orion v1.3 and its LBX data files, either placed alongside the executable or in a directory referenced by the included documentation. Windows/MSDOS users can extract a release archive directly into their MOO1 folder; Linux requires SDL and SDL_mixer (SDL2 variants also supported); Android play is possible via DOSBox with a DPMI extension. Older save files may not carry over across versions.

History

The original 1oom was created by a developer using the pseudonym 'Kilgore Trout Mask Replicant' and released as free software. This repository is a fork restoring and continuing that work after it fell into a broken state; a separately maintained 'vanilla' fork (1oom v2.0) also continues development from the same base.

Known issues & limitations

• compatibility: Older saved games may not work in newer versions of 1oom due to breaking changes.
