FreeDiskSysROM aims to provide a replacement for the original FDS BIOS (often referred to as disksys.rom) that can be freely redistributed and that is capable of running all published FDS software. FreeDiskSysROM is not currently fully completed and may not be sufficient for some FDS software. To track its status, consult https://github.com/jamesathey/FreeDiskSysROM?tab=readme-ov-file#apis.

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.

RPCS3 is an emulator and debugger for the Sony PS3.

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

Mupen64Plus is a cross-platform plugin-based Nintendo 64 (N64) emulator which is capable of accurately playing many games. This package contains the Glide64 video plugin.

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.

This package provides a collection of Vulkan GLSL (.slang) shaders for use with RetroArch.

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

This package provides game-specific widescreen and de-interlacing patches for use with PCSX2.

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-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).

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

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.

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.

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.

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

This is a part of the TiLP project.

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.

GNUSim8085 is a graphical simulator, assembler, and debugger for the Intel 8085 microprocessor.

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.

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.

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.

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