Free emulator software for linux

DeSmuME project is a Nintendo DS emulator that can run both commercial games and homebrew applications.

The original author of DeSmuME is YopYop156. He has stopped working on it on the beginning of april 2006 and passed the torch to a new team of developers. You can now follow the progress of DeSmuME on this site.

ggiterm is a terminal emulator which uses the platform-agnostic GGI library for its input and display.
This enables ggiterm to be run unmodified on any target supported by GGI, including X Window, the Linux framebuffer, Windows and more exotic setups...
Ever dreamed of typing your command lines on a fully anti-aliased, unicode-enabled, 3x3 TV display wall?
Main features:
- Anti-aliased rendering through Freetype
- Side effect of the above: use any font format supported by Freetype (TrueType, Type1, ...)
- Fully internationalized
- Backward compatible with the widespread DEC vt100 terminal
- Multiple architectures support
Enhancements:
- Tremendous speedups in this release. Many longstanding bugs have been fixed as well. It is not bug free, but I think our patient users have been waiting for an update long enough...

SharpNES is a clean-room NES emulator using SDL and GTK#.
SharpNES supports:
- A number of NES mappers
- SaveRAM using the .sav files other NES emulators use
- Play/pause
SharpNES is 100% clean room, no proprietary information was harmed in the making of this emulator.

PHPterm is a terminal/shell emulator for PHP which lets you execute shell commands just like in a shell, but all within your browser window over the HTTP protocol.

It aims to provide the look and feel of konsole, the KDE terminal.

LegaSynth is an old chip and synthethizer emulator.

Current engines proovide very precise emulation of:

- Yamaha DX7 FM
- MOS6581 Sound Interface Device (or best known as the good old C64 SID :)
- Yamaha YMH2K series (Soundchip very popular in small Yamaha keyboards/Arcades and the Sega GENESIS)
- TB303 - Still needs some work, but its perfectly usable.

LegaSynth Programming Framework:

- LegaSynth is also a very powerful synthethizer programming framework, where, with only a few lines of code you can have your own engine going.
- A simple demo engine and some documentation are aviable within the source tarball.
- The difference between LegaSynth and other programs such as Reaktor, Bristol, PD, csound,etc is that here the engines have to be actually programmed and optimized by hand, this way legasynth achieves unparalleled speed and polyphony.

QTVBA project is a graphical frontend to the VisualBoyAdvance Nintendo Gameboy Advance Emulator.
Main features:
- dual screenshot handling
- save game information
- number and last date played recording
- a built in ROM renamer
- compatibility with GBA-Shells screenshot formats and indexing

Kamefu is the collection manager and emulator frontend for KDE. The direct inspiration for this application is the audio player amaroK. It supports emulators for systems like MAME, NES, SNES, Nintendo 64, Game Boy Advance, Master System, Megadrive, PC Engine and more.
Planned features are:
Configuration for each emulator is handled by modules created with a script language like Python, Perl and Kommander. The collection manager can check if your games are valid via an XML database. New emulator configuration modules and databases can be downloaded with KHotNewStuff.
Supported systems(as 0.1):
- NES (Nintendo Entertainment System)
- SNES (Super Nintendo Entertainment System)
- GB/GBC (Game Boy/Game Boy Color)
- GBA (Game Boy Advance)
- MAME (Multiple Arcade Machine Emulator)

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.
