The Jolly Good Reference Frontend (accessible via the jollygood command) aims to be the simplest possible frontend to The Jolly Good API. It may be used to run emulators built as shared objects, or as a "white-label" frontend for statically linked standalone emulators.

The DOSBox Staging project attempts to modernize DOSBox.

DOSBox emulates an Intel x86 personal computer running an IBM PC compatible disk operating system (DOS) in both real and protected modes. It was primarily designed to run old DOS games, but aims to be fully compatible with all DOS programs and replicate the experience as accurately as possible.

This fork fixes some perceived issues with DOSBox and adds new features such as Wayland support, PowerPC/POWER dynamic recompilation, and FluidSynth MIDI. Other features may be removed: for example, physical CDs can no longer be played, only emulated media.

Graphical emulation includes contemporary text mode, Hercules, CGA, EGA, VGA, VESA, S3 Trio 64, and Tandy hardware.

Emulated legacy sound devices range from a rudimentary `PC speaker' buzzer to the once state-of-the-art Gravis Utrasound sampling sound card. The default is a SoundBlaster 16 providing 16-bit stereo sound. MIDI is forwarded to the host through an emulated MPU-401.

An emulated hardware modem is also included, letting one host or dial a BBS across the Internet, network over IPX, and emulate a serial nullmodem over TCP/IP.

This package contains a MIPS CPU emulator. The simulator accepts ELF statically linked executables compiled for 32-bit big-endian MIPS target, targeting mips-linux-gnu or mips-elf.

Gens/GS is an emulator for the Mega Drive (also known as Sega Genesis), derived from Gens. Project goals include clean source code, combined features from various forks of Gens, and improved platform portability.

Flycast is a multi-platform Sega Dreamcast, Naomi, Naomi 2, and Atomiswave emulator derived from reicast.

This is a versioned snapshot of the files containing metadata about each known libretro core. The snapshot is taken from the libretro-super repository.

PPSSPP is a ``high-level'' emulator simulating the PSP operating system.

This program compresses files in a way that tries to be as efficient as possible but still allows them to be decompressed in environments where CPU speed and RAM are limited. It also generate a self-extractor for use on a Commodore C64, C128 etc.

VICE is a program that emulates the C64, the C64DTV, the C128, the VIC20, practically all PET models, the PLUS4 and the CBM-II (aka C610/C510). An extra emulator is provided for C64 expanded with the CMD SuperCPU.

This package provides an assembler and emulator for the Uxn stack-machine, written in ANSI C. Graphical output is implemented using SDL2.

Nestopia UE (Undead Edition) is a fork of the Nintendo Entertainment System (NES/Famicom) emulator Nestopia, with enhancements from members of the emulation community. It provides highly accurate emulation.

Blastem is an emulator for the Sega Genesis/Mega Drive console.

melonDS is an emulator for the Nintendo DS handheld gaming console. It aims to support Nintendo DSi and 3DS as well.

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

Mupen64Plus is a cross-platform plugin-based Nintendo 64 (N64) emulator which is capable of accurately playing many games. This package contains the Z64 RSP processor plugin.

MAME's purpose is to preserve decades of software history. As electronic technology continues to rush forward, MAME prevents this important vintage software from being lost and forgotten. This is achieved by documenting the hardware and how it functions. The source code to MAME serves as this documentation.
