Free powerpc platform emulator software for linux

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...

Boycott Advance is a SDL based Gameboy Advance Emulator.
Boycott Advance/SDL is based on the BA core, with one essential difference: it uses the Simple Direct Media Library rather than the DirectX libraries. Consequently, it can be used on many different platforms, while still using the excellent BA core.
Unlike the original BA, BA/SDL doesnt have any GUI(except for the BeOS version), though for those who dislike commandline programs there are several frontends available (see download section).
Enhancements:
- Completely insync with BoyCott Advance v0.2.8;
- Incorperated the new sdlemu library;
- BoyCott Advance sdl-core is completely rewritten for use of the new sdlemu library;
- Many bugfixes and code enhancements (somewhat speedier);
- Many filter options to a total of 19(!) different SDL filters;
- Optimized OpenGL and SDL rendering options;
- And many changes which are infact to many to note!;

KStella is a KDE frontend to the Atari 2600 emulator, Stella. It currently supports the display of snapshots, labels, manuals, the configuration of individual game settings and of course, the ability to play games with just a click of the mouse.
All these features are fully customizable to allow maximum flexibility.
KStella is NOT an emulator. It is merely a frontend to Stella, a multi-platform, Atari 2600 emulator.
Enhancements:
- Fixed a bug where ROMs with the #" symbol wouldnt appear in the ROM list.
- Added a progress dialog box when loading ROM information from disk.
- Fixed problem with compiling on Mandrake 9.2 when using older versions of QT.
- Finally fixed the long-standing bug where KDE items (icons, rc files, etc.) would be installed in the wrong places. This was due to a bug in the configure script generated by KDevelop. Thats what I get for relying on a GUI development environment.
- Tested this release on Mandrake 9.2 and 10.0, Libranet 2.8.1 (Debian) and Suse 9.0.

Mupen64 is a n64 emulator desgined to be multi-OS. It has been developped on/for Linux originally but the emulator has already been ported succesfully on Windows and MacOSX for example. Actually the program can be easily ported on all OS supported by the SDL library.

mupen64 emulator is highly compatible and uses a plugin system. With the correct plugins (``correct can be computer dependent), it can achieve nearly perfect graphics and sound in many games.

The biggest problem of this emulator until now was its speed but now its progressively changing with a totally new core and theres still a huge room for improvements. Anyway if you have a fast machine, you should already be able to get many games running fullspeed.

jcinc is an emulator for the Bell Labs CARDIAC (Cardboard Illustrative Aid to Computation) computer.
The CARDIAC kit was published in 1969 to teach the internal workings of a digital computer and machine code programming.
jcinc emulates the CARDIAC computer and allows the user to run CARDIAC programs.
Enhancements:
- Single step mode and button controls.

Cross Platform Toolkit Library (xtklib) is a C++ based framework for highly object-oriented cross-platform programming.
In particular, the library provides a full abstraction layer between its API and the main services offered by the underlying operating system(Thread, processes,GUI,Filesystem,etc.) plus a set of generic utilities (Strings,Data structures,etc.).
Unlike other famous libraries, xtklib makes full use of all features of C++ like RTTI, Templates, Exceptions thus obtaining a strongly object-oriented design with a Java-like sensation.
The library is composed by two main modules: "Base" and "Widgets". The target operating systems are Windows and Unix(Linux and BSD in primis) with a plan to move also towards other systems.
Main features:
- Use of modern C++ - use of many powerfull features offered by modern C++ like exceptions,RTTI,templates and namespaces allows faster development,improves code readability,and reduces programming errors.
- Strong Object-Oriented design - designed to meet requirements of modern software industry: modularity, low coupling, high cohesion,information hiding. Design patterns and advanced class hierarchies are extensively used in all the library.
- Ease of use - Clean and intuitive programming interface with a Java-like sensation.
- Complete - Features supported includes:
- Basic services: Thread, Synchronization, Filesystem access, Processes, Networking.
- Advanced services: I/O Streams, Logging.
- Debugging tools: Stack tracing, Memory Leak detection.
- Gui widgets (Work in progress): Windows,Frames,Layout managers,common controls,advanced controls.
- Generic utilities: complete data structures framework, String class with unicode support.
- Full unicode support: native support to unicode, conversion to/from different charsets.
- And many others: the list is too much long to enumerate all minor but extremely usefull features.
- Cross Platform - Supports various systems and compilers.
- XTKlib is known to work under:
- Windows XP (x86)
- Visual C++ versions 7.1, 8.0
- MinGW32
- Linux (x86, x86_64)
- GCC 3.4
- Compatibility with other platforms and compilers are not excluded.(If you can compile/use xtklib with a non listed compiler/platform let us know about that, thanks)
- Fast - Although performance are not the main goal of this library (exceptions and RTTI have a tradeoff in this meaning), code agility and execution speed are often taken in consideration during development, thus leaving a performance advantage compared to interpreted programming languages(eg. Java,C#) or scripting languages(eg. Python,Ruby,Perl).
Enhancements:
- This is the first release with a working "Widgets" module, although it has only basic features.
- This release is provided for testing and development only.

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
