Libretro is a simple but powerful development interface that allows for the easy creation of emulators, games and multimedia applications that can plug straight into any libretro-compatible frontend. RetroArch is the official reference frontend for the libretro API, currently used by most as a modular multi-system game/emulator system.

LowRES NX is a simulated retro game console, which can be programmed in the classic BASIC language. This package provides a libretro core allowing the lowRES NX programs to be used with libretro frontends such as RetroArch.

DeSmuME is an emulator for the Nintendo DS handheld gaming console.

ScummVM is a program which allows you to run certain classic graphical point-and-click adventure games, provided you already have their data files. The clever part about this: ScummVM just replaces the executables shipped with the games, allowing you to play them on systems for which they were never designed!

This package provides joypad autoconfig files for RetroArch, the reference frontend for the libretro API. The autoconfig files are used to recognize input devices and automatically setup default mappings between the physical device and the RetroPad virtual controller.

SameBoy is a user friendly Game Boy, Game Boy Color and Super Game Boy emulator. SameBoy is accurate and includes a wide range of debugging features. It has all the features one would expect from an emulator---from save states to scaling filters.

mGBA is an emulator for running Game Boy Advance games. It aims to be faster and more accurate than many existing Game Boy Advance emulators, as well as adding features that other emulators lack. It also supports Game Boy and Game Boy Color games

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.

A standalone port of Mednafen’s GameBoy Advance emulator called Beetle GBA to libretro. Beetle GBA is based on VBA-M, itself a fork of Visual Boy Advance.

FCEUX is a Nintendo Entertainment System (NES), Famicom, Famicom Disk System (FDS), and Dendy emulator. It supports NTSC (USA/JPN), PAL (European), and NTSC-PAL Hybrid modes. It also offers tools for debugging, rom-hacking, map making, Tool-assisted movies, and Lua scripting.

PCSX2 is a free and open-source PlayStation 2 (PS2) emulator. Its purpose is to emulate the PS2's hardware, using a combination of MIPS CPU interpreters, recompilers and a virtual machine which manages hardware states and PS2 system memory. This allows you to play PS2 games on your PC, with many additional features and benefits.

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.

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.

Mednafen is a portable, utilizing OpenGL and SDL, argument-driven multi-system emulator. Mednafen has the ability to remap hotkey functions and virtual system inputs to a keyboard, a joystick, or both simultaneously. Save states are supported, as is real-time game rewinding. Screen snapshots may be taken, in the PNG file format, at the press of a button. Mednafen can record audiovisual movies in the QuickTime file format, with several different lossless codecs supported.

The following systems are supported:

• Apple II/II+

• Atari Lynx

• Neo Geo Pocket (Color)

• WonderSwan

• GameBoy (Color)

• GameBoy Advance

• Nintendo Entertainment System

• Super Nintendo Entertainment System/Super Famicom

• Virtual Boy

• PC Engine/TurboGrafx 16 (CD)

• SuperGrafx

• PC-FX

• Sega Game Gear

• Sega Genesis/Megadrive

• Sega Master System

• Sega Saturn (experimental, x86_64 only)

• Sony PlayStation

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.

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.

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.

Inspekt3d is a lightweight 3D viewer for Libfive written in Guile Scheme. The viewer can be used interactively with a REPL (for example Geiser in Emacs).

Cutter is a reverse engineering platform powered by rizin. It aims to be an advanced and customizable reverse engineering platform while keeping the user experience in mind. Cutter is created by reverse engineers for reverse engineers.

cutecom is a graphical serial terminal, like minicom. It is aimed mainly at hardware developers or other people who need a terminal to talk to their devices.

The libspnav library is provided as a replacement of the magellan library. It provides a cleaner, and more orthogonal interface. libspnav supports both the original X11 protocol for communicating with the driver, and the new alternative non-X protocol. Programs that choose to use the X11 protocol, are automatically compatible with either the free spacenavd driver or the official 3dxserv, as if they were using the magellan SDK.

Also, libspnav provides a magellan API wrapper on top of the new API. So, any applications that were using the magellan library, can switch to libspnav without any changes. And programmers that are familiar with the magellan API can continue using it with a free library without the restrictions of the official SDK.

Microcom is a minimalistic terminal program for accessing devices via a serial connection. It features connection via RS232 serial interfaces (including setting of transfer rates) as well as in telnetmode as specified in rfc2217 and a (Linux specific) CAN mode.
