Mupen64Plus is a cross-platform plugin-based Nintendo 64 (N64) emulator which is capable of accurately playing many games. This package contains the SDL audio plugin.

bsnes-hd (called ``HD Mode 7 mod, for bsnes'' in early betas) is a fork of bsnes (the great SNES emulator by Near) that adds HD video features, such as:

HD Mode 7

Renders the rotated, scaled or pseudo perspective backgrounds at higher resolutions. This does not involve new custom imagery or upscaling algorithms. It is a higher resolution version of the process the SNES uses.

Widescreen

Extends the scenes to the left and right, without distorting them. It works for most Mode 7 scenes, but also for some other scenes/games, after some settings tweaking.

True color

Color calculation are done at true color instead of the SNES color depth (3x8 instead of 3x5 bit). With the optional line color smoothing color ``steps'' turn into actual gradients (without influencing the sharpness of the artwork).

higan is a multi-system emulator with an uncompromising focus on accuracy and code readability.

Beetle PSX is a port/fork of Mednafen's PSX module to the libretro API. Additional features include PBP/CHD file format support, high-resolution software rendering, OpenGL and Vulkan renderers, and PGXP perspective correct texturing. For those seeking improved visuals and performance, Beetle PSX HW provides a hardware-accelerated alternative with its OpenGL and Vulkan renderer.

Mupen64Plus is a cross-platform plugin-based Nintendo 64 (N64) emulator which is capable of accurately playing many games. This package contains the command line user interface. Installing this package is the easiest way towards a working Mupen64Plus for casual users.

bsnes-jg is a cycle accurate emulator for the Super Famicom/Super Nintendo Entertainment System, including support for the Super Game Boy, BS-X Satellaview, and Sufami Turbo. bsnes-jg is a fork of bsnes v115, Many changes have been made post-fork:

• Higher quality resampler with settings

• Improved performance without loss of accuracy

• Portability improvements

• Removal of accuracy-reducing hacks and unnecessary code

• Significant increase in standards compliance

• Translation to the C++ Standard Library (ISO C++11)

In particular, it uses much less CPU compared to the original bsnes (though not as little as zsnes).

The supported file formats are:

• .sfc

• .smc

• .bs

• .st

• .fig

• .swc

This is intended to be used with the Jolly Good Reference Frontend jollygood command from the jgrf package.

Stella is a multi-platform Atari 2600 VCS emulator, released as Free Software. Enjoy all of your favorite Atari 2600 games on your PC thanks to Stella!

This package contains libticonv, a library to support working with TI calculator files.

This is a part of the TiLP project.

Uniforn is a lightweight, multi-platform, multi-architecture CPU emulator framework based on QEMU.

Enchant is a library---and command-line program---that wraps a number of different spelling libraries and programs with a consistent interface. By using Enchant, you can use a wide range of spelling libraries, including some specialized for particular languages, without needing to program to each library's interface. If it's not convenient to call a C library, you can access most of Enchant's functionality via the enchant program, which communicates over a pipe, like Ispell, and is indeed Ispell-compatible.

PyEnchant is a spellchecking library for Python, based on the Enchant library. PyEnchant combines all the functionality of the underlying Enchant library with the flexibility of Python. It also provides some higher-level functionality than is available in the C API.

Nuspell is a fast and safe spelling checker software program. It is designed for languages with rich morphology and complex word compounding. Nuspell is written in modern C++ and it supports Hunspell dictionaries.

Kicad is a program for the formation of printed circuit boards and electrical circuits. The software has a number of programs that perform specific functions, for example, pcbnew (Editing PCB), eeschema (editing electrical diagrams), gerbview (viewing Gerber files) and others.

Gaf stands for “gschem and friends”. It is a subset of the entire tool suite grouped together under the gEDA name. gEDA/gaf is a collection of tools which currently includes: gschem, a schematic capture program; gnetlist, a netlist generation program; gsymcheck, a syntax checker for schematic symbols; gattrib, a spreadsheet programme that manipulates the properties of symbols of a schematic; libgeda, libraries for gschem gnetlist and gsymcheck; gsch2pcb, a tool to forward annotation from your schematic to layout using PCB; some minor utilities.

Valeronoi (Valetudo + Voronoi) is a companion for Valetudo for generating WiFi signal strength maps. It visualizes them using a Voronoi diagram.

GPX is a post processing utility for converting gcode output from 3D slicing software to x3g files for standalone 3D printing on common 3D printers.

GNU poke is an interactive, extensible editor for binary data. Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them.
