Free emulator downloads software for linux

Retriever Download Manager program was written completely in the Java programming language and will run on any operating system with a Java Virtual Machine installed (JVM 1.4 or higher).
Retriever allows you to download files from the internet easier and with more control than from your web browser, with it you can resume interrupted downloads at any time thats convenient or even schedule downloads to occur when youre away from your computer. Even if one server is too busy to accomodate you Retriever will automatically switch to another to continue your download.
You can even temporarily pause your download and resume it instantly a few minutes later.
No matter how many times your download is interrupted or stopped Retriever gives you a successful download.
Retriever is highly reliable and customizable.
Downloads can be input manually into the program or captured from the clipboard.
You can also drag and drop links onto the download list to capture them. If a selection of text is dropped, it will be parsed for links, you can use this behaviour to add multiple files at once.

- Fixed problem with FTP servers that did not use the default port.
- Fixed issue where status information would be incorrect.

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.

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.

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.

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.
