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.

Nestopia JG is an emulator for the Nintendo Entertainment System/Famicom, including support for the Famicom Disk System and VS. System. Though originally a fork, Nestopia JG has become the de facto upstream branch of the Nestopia emulator.

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.

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

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.

Gnome Arcade is a minimal GTK+ frontend for MAME, the multi-purpose arcade and console emulator.

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.

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

Provides a backport of Python's StrEnum class which was introduced in Python 3.11 for Python >=3.8.6.

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.

emu8051 is a simulator of the 8051/8052 microcontrollers.

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.

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.

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.

mbpoll is a command line utility to communicate with ModBus slave (RTU or TCP).

Libctl is a Guile-based library implementing flexible control files for scientific simulations.

Lib3ds is a toolkit for handling the 3DS format for 3D model files. Its main goal is to simplify the creation of 3DS import and export filters.

Uranium is a Python Framework for building 3D printing related desktop applications using PyQt5. It belongs to the Cura project from Ultimaker.

Harminv is a free program (and accompanying library) to solve the problem of harmonic inversion — given a discrete-time, finite-length signal that consists of a sum of finitely-many sinusoids (possibly exponentially decaying) in a given bandwidth, it determines the frequencies, decay constants, amplitudes, and phases of those sinusoids.
