Wide Area Link Emulator enables you to set and test various parameters of a WAN access link (also known as a bottleneck link) before testing on a fully-functional network.

Any ISP has a high bandwidth LAN (of the order of tens of Mbps, e.g. Ethernet) and a WAN access link with relatively low speeds (of the order of a few Kbps to a few Mbps). To be able to evaluate the ISPs performance, actual tests will have to be conducted on a live, fully functional network. This would imply enabling certain features in communication equipment which could be detrimental to the proper functioning of a commissioned network. To address such a problem of being able to characterize/quantify the network operation in terms of its performance with respect to various parameters, a test-bed emulating the ISPs connectivity to the Internet would be an ideal solution.

An important factor in setting up such a test-bed, is emulating the WAN Access Link. Using complex hardware is costly. Such a link can however be easily implemented by emulating the scenario on popular physical technology such as Ethernet. By changing the TCP/IP stack on a Personal Computer, the rate at which packets are injected into the network can be controlled and other necessary features can easily be added.

WALE was implemented in 2 phases and the first version can emulated bandwidths up to 8Mbps and uses FIFO queues with drop-tail.

WALE v2 can emulate bandwidths of up to 80Mbps(a 10-fold improvement over version 1) due to the stripped down version of Micro-second resolution timer being used in the Linux kernel. WALE also implements differentiated services are recommended by IETF. A hash-based packet classifier is used to classify packets into one of 3 queues (Expedited Forwarding, Assured Forwarding and Best Effort). A simple priority scheduling has been implemented between the queues.

Version 2 has been implemented in the Generic Device Layer of the Linux Kernel. The kernel version is 2.2.19. WALE2 kernel patch can be downloaded here. An ncurses based front end has been implemented for setting and viewing various parameters of the bottleneck link.

Unix Amiga Delitracker Emulator (UADE) plays most Amiga music file formats by simulating Amiga hardware and software.
Unix Amiga Delitracker Emulator plays over 180 Amiga music file formats and has three frontends for playing: a command line tool, an XMMS plugin, and a Beep Media Player frontend.
Enhancements:
- An improved version of the Special FX replayer was added.
- A new Special FX ST replayer was added.
- Bugs in song length database handling were fixed.
- Audacious 1.3 is supported.
- 15 instrument soundtracker module detection is supported.

Crate Game Engine is a game engine that is designed to make the process of creating games trivial.
The rendering engine and scripting engine are removed from the game engine to make the specialization of games as easy as possible.
An XML game loader will be implemented to make creating games require no recompiling.
Extremely easy to use game engine with modular Scripting and Rendering engines.
Milestones:
Milestone 1: Basic framework compilable (completed Oct 9, 2005)
Milestone 2: C++ proof of concept demo using framework & text based RenderingEngine
Milestone 3: XML based game loader with Milestone 2 game ported to it
Milestone 4: Scripting support with Milestone 3 game ported to it
Milestone 5: 2D Rendering Engine with Milestone 4 game ported to it
Enhancements:
- This release includes minor API and documentation updates, as well as a logging system.

FCE Ultra is a NES (Nintendo Entertainment System) and Famicom (Family Computer) emulator for a variety of different platforms, based on Beros FCE. Game compatibility is very high, provided you provide non-corrupt ROM/disk images.
It has been tested (and runs) under DOS, Linux SVGAlib, Linux X, Mac OS X, and MS Windows. A native GUI is provided for the MS Windows port, and the other ports use a command-line based interface. The SDL port should run on any modern UNIX-like operating system(such as FreeBSD) with no code changes.
Enhancements:
- Latest code found on the net.

Easy Game Library is library of C++ classes designed to make game programming easier. Now it consists only of easy_sprite library which consists of classes for using sprites.

It should compile on different platforms because it uses SDL library as backend.

Installation:

To install run such sequence of commands:

make - Compiles library and tests

make install - Installs library and tests
