2025 UPDATE: we have finally moved to Git! https://forge.a-lec.org/speed-dreams/speed-dreams-code/ This SourceForge project will be kept as a read-only archive and will be eventually removed! Speed Dreams is a Motorsport Simulator featuring high-quality 3D graphics and an accurate physics engine, all targeting maximum realism. Initially forked from TORCS, it has now reached a clearly higher realism level in visual and physics simulation, thanks to its active development team and growing community. It mainly aims to implement exciting new features, cars, tracks and AI opponents to make a more enjoyable game for the player, while constantly pushing forward visual and physics realism. It is also intended for any research, study or teaching activity, around physics and AI, thanks to its GPL V2+ license, and the clear and modular architecture of its C/C++ code base.

Trigger Rally
A fast-paced free software rally racing game
A 3D rally simulation with a great physics engine for drifting, over 200 maps, different terrain materials like dirt, asphalt, sand, ice etc. and various weather, light and fog conditions give this rally simulation the edge over many other free games. You need to make it through the maps in often tight time limits and can further improve by beating the recorded high scores. All attached single races must be finished in time in order to win an event, unlocking additional events and cars. Most maps are equipped with spoken co-driver notes and co-driver icons. Many configuration details for display and audio adjustments can be edited in the well documented plain text configuration file. Additional contributed maps and events are ready for download as plugins. Trigger Rally works well with common low performance laptops from about 2008. And if something like snow flakes and vegetation sprites demand to much from your system you can just disable it. -

Sims 3 Package Interface
Sims 3 (and other) game package library
"Sims 3 Package Interface" provides a core library of portable code that "understands" Sims3 game packages. Note that (with some minor tweaks) the core library code also understands other game package formats (e.g. SimCity Online, Sims4). Along with the core library are a number of "wrappers" that provide the main part of the project. These handle deserialization and serialization of data within the package (or any other source). Further tools (not supplied here) can use the core library and wrappers to manipulate the data content of package files. Note that development on this library and wrappers provided here has now finished.">
