OpenSpin is a compiler for the Spin/PASM language of the Parallax Propeller. It was ported from Chip Gracey's original x86 assembler code.

This package provides a firmware programmer for the STM32 Discovery boards. It supports two versions of the chip: ST-LINK/V1 (on STM32VL discovery kits) and ST-LINK/V2 (on STM32L discovery and later kits). Two different transport layers are used: ST-LINK/V1 uses SCSI passthru commands over USB, and ST-LINK/V2 and ST-LINK/V2-1 (seen on Nucleo boards) use raw USB commands.

This package provides a library in order to support the MPSSE (Multi-Protocol Synchronous Serial Engine) adapter by FTDI that can do SPI, I2C, JTAG.

This is a C library for the Parallax Propeller micro-controller.

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.

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.

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 contains libticonv, a library to support working with TI calculator charsets.

This is a part of the TiLP project.

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.

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.

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.

ScummVM is a program which allows you to run certain classic graphical point-and-click adventure games, provided you already have their data files. The clever part about this: ScummVM just replaces the executables shipped with the games, allowing you to play them on systems for which they were never designed!

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.

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

This package provides joypad autoconfig files for RetroArch, the reference frontend for the libretro API. The autoconfig files are used to recognize input devices and automatically setup default mappings between the physical device and the RetroPad virtual controller.

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

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

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