GLideN64 is a new generation graphics plugin for Nintendo 64 emulators, which offers better performance and compatibility compared to the original Glide64 plugin. This version is built for use with the Mupen64Plus emulator.

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.

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.

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.

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

RetroArch incorporates a ROM scanning system to automatically produce playlists. Each ROM that is scanned by the playlist generator is checked against a database of ROMs that are known to be good copies. The various directories contain:

cht

Cheat codes for various games

cursors

Methods for querying the playlists

dat

Customized DAT files, maintained by the libretro team

metadat

Different metadata and third-party DATs available to the system

rdb

The compiled RetroArch database files

scripts

Various scripts that are used to maintain the database files.

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).

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

Keystone is a lightweight multi-platform, multi-architecture assembler framework. It supports a wide-range of different architectures and offers an intuitive architecture-neutral API for interacting with assembly for these architectures.

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

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.

Dolphin is an emulator for two Nintendo video game consoles: the GameCube and the Wii. It provides compatibility with all PC controllers, turbo speed, networked multiplayer, and graphical enhancements.

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.

This package provides a development environment for 6502 systems, including macro assembler, C compiler, linker, librarian and several other tools.

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