1oom

1oom aims to accurately reproduce the original DOS version of Master of Orion (1993) in a form that can be run on modern computers. 1oom is Free Software (GPLv2), see COPYING.

1 Installation

1oom requires a copy of the Master of Orion (v1.3) LBX files.

1.1 Windows, MSDOS

Simply extract the desired release to your MOO1 directory. Alternatively copy your MOO1 LBX files (and saved games if needed) to your 1oom directory. See usage_common if you prefer to use a separate directory.

1.2 Unix (Linux)

1oom requires the following libraries:

• SDL (libsdl1.2 or libsdl2): http://www.libsdl.org
• SDL_mixer (libsdl-mixer1.2 or libsdl2-mixer): http://www.libsdl.org/projects/SDL_mixer/

Also recommended:

• libsamplerate: http://www.mega-nerd.com/libsamplerate/

Check your distribution's package manager or the library website on how to install them.

1.3 Android (DOSBox)

To play on Android you will need the 1oom executable for MSDOS, DOSBox application for Android and DPMI extension, for example CWSDPMI. You can build the 1oom executable for MSDOS using i586 DJGPP and Allegro4.

2 Configuration

See usage_common.

3 Development

See COMPILING and HACKING for more information.

4 Executables

1oom consists of a few executables:

• 1oom_classic_* (the 1993 UI)
• 1oom_cmdline (proof of concept textual UI)
• 1oom_lbxview_* (for viewing LBX files)
• 1oom_lbxedit (for editing LBX files)
• 1oom_pbxmake (for creating PBX files)
• 1oom_pbxdump (for dumping PBX files)
• 1oom_gfxconv (for converting GFX for use in PBX files)
• 1oom_saveconv (for converting save game files)
• 1oom_*_sdl1 (using SDL 1.2.x)
• 1oom_*_sdl2 (using SDL 2.x)
• 1oom_*_alleg4 (using Allegro 4.x)

See usage_common for common documentation.

Some ports have shorter filenames due to filesystem limitations.
