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

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!

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.

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

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.

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 timezone data in the format expected by Nintendo Switch emulators. It converts standard IANA timezone data to the Nintendo Switch's proprietary format.

This package provides an emulator for the Uxn stack-machine. Graphical output is implemented using X11, and its Console device contains a exec port to interface with the host system.
