Aleph One

* Aleph One

This is a new port of Aleph One engine for AmigaOS 4. Aleph One engine
allows you to play Marathon, Marathon Infinity and Marathon 2 games.

* Features

Port supports software rendering and "classic" OpenGL renderer. SW
rendering is of course CPU-based, but it's also possible to choose the
"compositing" backend which accelerates the scaling from the internal resolution
to the final resolution.

OpenGL renderer requires a working MiniGL installation (and Warp3D).
There seems to be some issues left which can be worked around. Disable "Z
buffer" and enable "3D objects" in the rendering options menu, otherwise sprites
may be invisible. 

* Installation

Data for Marathon games is available here: https://alephone.lhowon.org/

Another link: https://github.com/Aleph-One-Marathon/alephone/releases

You should unpack them into corresponding directories, copy "alephone" binary
to the same place and start the game.

* Source code

Some modifications, work arounds and fixes were done to get this game running.
Source code is available here: https://github.com/capehill/alephone

* Bugs

Surely there isn't one but just in case, use the GitHub bug tracker...

* License

Aleph One is licensed under GPL v 3.

This port is _statically_ linked (sorry about that) to various libraries, such
as SDL2, SDL2_ttf, SDL2_net, freetype, z, Ogg, Vorbis and Vorbisfile.
