The FreeCol team aims to create an Open Source version of Colonization (released under the GPL). At first we'll try to make an exact clone of Colonization. The visuals will be brought up to date with more recent standards but will remain clean, simple and functional. Certain new 'features' will be implemented but the gameplay and the rules will be exactly the same as the original game. Examples of modern features are: an isometric map and multiplayer support.This clone will be developed incrementally and result in FreeCol 1.0.0 which will be an almost exact Colonization clone. Incremental development basically means that we'll add features one at a time. This allows us to have a running program at all times and also to release an unfinished but working game once in a while.Once FreeCol 1.0.0 is finished we'll start working towards FreeCol 2.0.0. FreeCol 2 will go beyond the original Colonization and will have many new features, it will be an implementation of our (and our users') image of what Colonization 2 would have been.

Hatari is an Atari ST/STE/TT/Falcon emulator for GNU/Linux, BSD, Mac OS X, Windows and other systems which are supported by the SDL library. The Atari ST was a 16/32 bit computer system which was first released by Atari in 1985. Using the Motorola 68000 CPU, it was a very popular computer having quite a lot of CPU power at that time. Unlike many other Atari ST emulators which try to give you a good environment for running GEM applications, Hatari tries to emulate the hardware of a ST as close as possible so that it is able to run most of the old ST games and demos. Hatari is open source software and is distributed under the terms of the GNU General Public License (GPL).Hatari supports the emulation of most of the ST and STE hardware, including some special tricks like raster interrupts, border effects and PSG sample sound. A joystick can be emulated with the cursor keys or with a real PC joystick. Hatari also features the possibility to "mount" a directory of the host system as a ST drive, or to use images from an original Atari's hard disk. Hatari is also able to emulate the additional hardware of the TT or Falcon machines, like the Videl video chip or the DSP 56001. However, note that TT and Falcon support are currently still in development and experimental.
