Free emulator software for linux

VT6530 Terminal Emulator is a Java implementation of the proprietary terminal used with Tandem mainframes.
The Tandem VT6530 is a proprietary terminal used with their Non-Stop(TM) series of mainframes. These high-reliability machines are popular in the banking industry. If youve ever used an ATM to get cash, youve probably used a VT6530.
The terminal itself can operate in three different mode: conversation, block, and ANSI (VT100). Conversation mode is a simple scrolling text mode with the addition key buffering and text attributes. In block mode, text is displayed in a formated screen with special edit fields. ANSI mode is only used with OSS, Tandems UNIX wanabe operating layer.
Enhancements:
- Autotools support (./configure, make, make check, and make install).
- New telnet and ANSI terminal implementations.
- Linux, Cygwin, and HP NonStop (tandem OSS) builds are not quite running yet.

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.

KBDE is a keyboard emulator. It allow emulate keyboard input for keyboardless x86 computers.
KBDE include following:
- linux kernel module
- user-space tools
- development library
Enhancements:
- Support was added for Linux kernel versions 2.6.20 and later.

MESSyFront is a frontend for the MESS emulator. MESSyFronts main goal of the project is to get the user in to the emulation environment as quickly as possible.

The secondary goal is targetting Tandy Color Computer users that run Linux (or *nix envrionments). As interest grows, other target environments may be added.

ckmame is a program to check ROM sets for MAME, the Multiple Arcade Machine Emulator.

ckmame project tells you which ROM files are missing or have a wrong checksum, and can delete unknown and unused files from the ROM sets, and rename or move ROM files.

Luit is a filter that can be run between an arbitrary application and a UTF-8 terminal emulator. It will convert application output from the locales encoding into UTF-8, and convert terminal input from UTF-8 into the locales encoding. It is mainly used to support xterm.

pLauncher project is an emulator front-end for multiple emulators.
pLauncher allows you to centralize all of your emulator/ROM launching needs.
It is open ended enough to allow the launching of any emulator (xmame, snes9x, xmess, vgb, dgen, WINE, etc.) and its ROMS/binaries.
Main features:
- Small and fast
- Works with any emulator
- Customizable views
- Easy to use
Enhancements:
- Added a rom count
- Added support for personal config file ~/.pLauncher
- Added graphical installer
- Fixed Help menu item to bring up HTML manual in Netscape (should be customizable in the future)
- Fixed bug which gave warning with no custom views
