Free nes emulator software for linux

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.

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.

Ultra NES Manager (UNM) is an application for managing "Nintendo Entertainment System" ROM files. It is also a frontend for "tuxnes" emulator.
It provides fast acces to your NES files, and helps you to set up "tuxnes" easily.
Usage:
UNM stores all your NES files in one directory ("~/.unm/roms" as default), and displays all of them on a main screen. It would be wise to copy some ROMs to that location.
To play some game you need to select it from the list of found ROMs on the main screen, and click on a "PLAY" button. A nes emulator will start the selected game. Options related to ROMs collection are located on "ROMs" tab, emulator options can be found on "Advanced tab". Have fun.
Enhancements:
- whole configuration is saved automatically after quitting the application
- recent played ROMs are now saved, so they appear even after program restart
- added tooltips for "Play!" tab
- added "Quit" button on "Play!" tab
- added confirmation dialog box at Esc keypress, so you wont quit your game accidentally (requires patching tuxnes)
- updated FAQ

GNOME FCE Ultra (also known as gfceu) is an interface for the popular Nintendo Emulator, FCE Ultra. GNOME FCE Ultra is designed for the GNOME desktop, and allows the user to easily play NES ROM images.
Main features:
- Network play
- Custom input configuration
- Fullscreen support
- Full sound support
- High compatibility and accurate emulation

GXemul is a machine emulator Im developing in my spare time.
GXemul project emulates processors and surrounding hardware components, in some cases well enough to allow unmodified "guest" operating systems to run inside the emulator as if they were running on a real machine.
MIPS:
- Several machine types are emulated well enough to run guest operating systems. NetBSD, OpenBSD, Linux, and even obscure things such as Ultrix and Sprite can run, to various degrees.
ARM:
- CATS is emulated well enough to run NetBSD and OpenBSD as guest OSes.
PowerPC:
- NetBSD/prep can run (experimental).
The emulator can be used for:
- experimenting with operating systems which you have not tried yet, or operating systems for hardware which you might not have access to,
- running guest operating systems for historical purposes, e.g. Ultrix or Sprite,
developing portable software, when you want yet another target platform to try to compile your software on (you can use GXemul to run a guest OS and compile your software inside that OS),
- development of new firmware or operating system code (but then you need to be aware of some limitations),
- educational purposes...
Enhancements:
- NetBSD/pmppc can now run in the emulator (with root on NFS).
- For ARM emulation (with NetBSD/cats, OpenBSD/cats, NetBSD/evbarm, or NetBSD/netwinder as the guest OS), the emulator does not use 100% of the hosts CPU if the guest OS is idle.
