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](COPYING).


1 Installation
===============

1oom requires a copy of the Master of Orion (v1.3) LBX files.
Please note that older saved games may not work in newer versions of 1oom.
Read the [changelog](CHANGES) to learn more about the breaking changes.

1.1 Windows, MSDOS
------------------

Simply extract the desired [release](https://github.com/1oom-fork/1oom/releases) to your MOO1 directory.
Alternatively copy your MOO1 LBX files (and saved games if needed) to your 1oom directory.
See [usage_common](doc/usage_common.txt) 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.
