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.

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.

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.

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

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).

This package provides the Jolly Good API C and C++ headers. The Jolly Good API is a shared object or plugin API for emulators.

Collection of classes that contain architecture-specific information information. Useful for cross-architecture tools (such as python-pyvex).

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

• A simple editor component with syntax highlighting.

• A keypad to input assembly language instructions with appropriate arguments.

• Easy view of register contents.

• Easy view of flag contents.

• Hexadecimal/decimal converter.

• View of stack, memory and I/O contents.

• Support for breakpoints for program debugging.

• Stepwise program execution.

• One click conversion of assembly program to opcode listing.

• Printing support.

• UI translated in various languages.

EmulationStation provides a graphical front-end to a large number of video game console emulators. It features an interface that is usable with any game controller that has at least 4 buttons, theming support, and a game metadata scraper.

This package contains libticables, a library for operations on TI calculator link cables.

This is a part of the TiLP project.

emu8051 is a simulator of the 8051/8052 microcontrollers.

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

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.

A PlayStation emulator based on PCSX-df Project with bugfixes and improvements.

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.

bsnes is a Super Nintendo / Super Famicom emulator that focuses on performance, features, and ease of use.

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

ZSNES is a Super Nintendo Entertainment System emulator that can play most games at full speed with sound and special graphic filters. Some of its features include:

• Support for smooth and dynamic image scaling

• Support for rewinding and fast-forwarding in-game

• JMA compression format

• Change the appearance of the GUI

• Take screenshots of currently running games

• Saving the game at any point by recording the console’s state

• Record movies of gameplay which can be played back.
