Biogenesis is an artificial life program that simulates the processes involved in the evolution of organisms. It shows colored segment based organisms that mutate and evolve in a 2D environment. Biogenesis is based on Primordial Life.

A 3rd-party tool to edit user files for the game FasterThanLight. With this, you can unlock any or all ships and achievements in your user profile, or tweak most aspects of saved games: crew, systems, weapons, fires, breaches, etc.

Corewar is a game played vicariously through the action of assembly language programs written in a language called Redcode. Corewar is discussed in the Usenet group REC.GAMES.COREWAR; the reference implementation of this game, pMARS, is maintained here.

VASSAL is a game engine for creating electronic versions of traditional board and card games. It provides support for game piece rendering and interaction, and supports play by email or over a live connection.

Tyrant is a graphical roguelike fantasy adventure game. It features intricate randomly generated landscapes, towns and dungeons. It is written in Java with a highly extensible game engine.

The very basic of a java 3D car driving game, freely expandable including a built-in basic 3D object editor and a more complex road+objects editor. Source code available, no OpenGL.

Extensible 3D (X3D) Graphics is a royalty-free International Standard for real-time interactive 3D graphics on the Web, providing unsurpassed interoperability for 3D communications on the Web. This project includes source for example X3D scene libraries and multiple X3D codebases produced by Web3D Consortium members. All open-source contributions are welcome.

JAS is a java library for creating agent based simulations. It features a discrete-event time engine, APIs for network simulation design, powerful yet easy-to-use implementations of Genetic Algorithms and Neural Networks.

A PSP porting of SUN's phoneMEAdvanced project (https://phoneme.dev.java.net/), to enable MIDP/PBP/JavaME applications running on PSP. You can also find phoneMEFeature PSP porting from another project: pspkvm(https://sourceforge.net/projects/pspkvm)

OpenPatrician is a free implementation in Java of Ascaron's classic The Patrician and The Patrician 2. The game is economic simulation located in the European North- and East-Sea in the late middle age.

A computer version of the World War 2 tactical boardgame "Squad Leader" originally published by The Avalon Hill Games Company. Play any scenario against anyone around the world!

XHSI (eXternal High-resolution Simulator Instruments) is an add-on for the X-Plane flight simulator. It displays the PFD, ND, EICAS, Flaps and Gear indicator, Clock/Chronometer, etc... in separate windows. In general, the instruments can be displayed in B737-NG or A320 style.

AdmIRC is a webmin module for irc server administration. It provides a config interface and advanced security and linking automatism support. Currently UnrealIRCD 3.2 and the services Anope and Epona are supported. Subprojects: irc newsbot and java tools

Multibody dynamics simulation package with frictional contact and collision detection

GaugeBook displays Gauges of your FSX (with SP2 or Acceleration) and gives you control over a lot of Settings. Change Frequencies, QNH, etc with a few mouse clicks. It's still beta but the new G1000 is a blast. Runs smooth on any notebook.

Worldlines visualizes special relativity, as particles near lightspeed trace paths in a 3D slice of 4D Minkowski spacetime. Scenes illustrate time dilation, the twin paradox, length contraction, and Bell's spaceship paradox.

The Kelpie Flight Planner for Flightgear. This Java based Gui flight planner uses the airport and navaid databases of the Flightgear, allowing the user to search for airports and navigation aids and plan flights between them. [Note: Requires Java 1.10 or above] This program is no longer being actively developed or supported. All future work is being undertaken on a port to Rust/Gtk at https://github.com/shartrec/kelpie-flight-planner. But is still in the very early stages.

Java-based free software for learning audio and flashing-light Morse code. Features include very flexible audio system, drills based on live news feeds, and adaptive drilling strategies.

An open source implementation of the Distributed Interactive Simulation (IEEE-1278) standard in C++, C-Sharp, Objective-C, Java, Javascript and XML. Example applications including sending and receiving native DIS traffic, X-Plane plugin, and WebSocket/Javascript/WebGL applications. See the individual code directories for each package of interest. This project is inactive and has migrated to a GitHub project at https://github.com/open-dis

A text-based soccer match generation engine. Reproduces the match with statistics and report. To be used as a library by integrating with 'host' applications. Download 'desktop' version or try it at http://www.pubsoccermanager.com

Tired of Football Mogul and its crappy game play and support? I am starting a java based American Football game. Any help is appreciated, even if you just want to create a player database or provide any helpful suggestions.

Bahamut-Sango is a historical-simulation game made by the fans. Now it is in processing.

An experiment in paired-programming to simulate elevator behaviour. Development is done entirely in Java. The finished product will provide a framework for additional simulations and some ability to test different elevator behaviours.

OpenBaseball will be a text-based baseball simulation using real data of baseball players. I hope to make the game statistically accurate in reproducing past seasons. I want it to be as statistically accurate as Diamond Mind Baseball.
