Free emulators for mac software for linux

UltraGetopt for Java is the Java imagening of UltraGetopt. The project provides the features and flexibility of UltraGetopt in a way that is more suited to the Java environment.
Main features:
- Supports MS-DOS formatted option strings (e.g. /option:arg)
- Provides parsing and error message compatibility with getopt from the GNU, (Open)BSD, and Mac OS
- Supports first-longest-matching for options
- Provides many configurable behaviors

cereal is an emulation framework designed to allow easy emulation of interconnected modules. Its main component is an 8051 emulator module, so it can be used as an 8051 emulator.

The reason for writing cereal was an 8051 embedded controller which should control an engine using pulse-width modulation, read the resulting flow from a flowmeter, and regulate the output to keep flow at a given value.

In the real world, it takes about two seconds for the algorithm to stabilize, and emulating two seconds using conventional emulators (computing the engine input, the real flow, the feedback frequency) by hand is simply impossible to do.

Using cereal, it took about two hours to create a module emulating the engine/flowmeter combination, along with a window showing the current values. Then it is trivial to connect this module to the 8051 module and just sit back and watch the result.

Another, more trivial example is a multiplexed display/keyboard combination (in my case, selecting one of four 8-segment LCD displays). Instead of watching the port bits, why not create a module that shows the output graphically as four displays?

In addition to these possibilities, cereal offers breakpoints, watches, evaluate/modify dialog (which can solve 2 * x + 1 = 5). The KDE GUI also can be extended using KParts (8051 interface is provided as a KParts plugin).

Also included is a command interface usable for creating testsuites for your programs (or for cereal itself - cereal has over 400 tests in its testsuite), and a simple 8051 disassembler.

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.

Not another MAC theme 0.1 provides you with a nice theme for GNOME users. It is actually a mix of all the MAC OS X GTK themes.

GNOME is an international effort to build a complete desktop environment the graphical user interface which sits on top of a computer operating system entirely from free software. This goal covers creating software development frameworks, selecting application software for the desktop, and working on the programs which manage application launching, file handling, and window and task management.

Requirements:

• GNOME

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.
