xSGE is a collection of modules that make doing certain tasks with the SGE Game Engine easier. In addition to SGE's conveniences, the user has access to a GUI toolkit, lighting and physics frameworks and Tiled TMX format support.

Chickadee is a game development toolkit for Guile Scheme built on top of SDL2 and OpenGL. Chickadee aims to provide all the features that parenthetically inclined game developers need to make 2D (and eventually 3D) games in Scheme, such as:

1. extensible, fixed-timestep game loop

2. OpenGL-based rendering engine

3. keyboard, mouse, controller input

4. REPL-driven development model

OpenVR is an API and runtime that allows access to VR hardware from multiple vendors without requiring that applications have specific knowledge of the hardware they are targeting.

Pygame is a set of Python modules designed for writing games. It adds functionality on top of the SDL library, allowing you to create games and multimedia programs in the Python language.

Pybox2d is a 2D physics library for your games and simple simulations. It's based on the Box2D library, written in C++. It supports several shape types (circle, polygon, thin line segments), and quite a few joint types (revolute, prismatic, wheel, etc.).

catcodec encodes and decodes sounds for OpenTTD. These sounds are not much more than some metadata (description and filename) and raw PCM data.

Ren'Py is a visual novel engine that helps you use words, images, and sounds to tell interactive stories that run on computers and mobile devices. These can be both visual novels and life simulation games. The easy to learn script language allows anyone to efficiently write large visual novels, while its Python scripting is enough for complex simulation games.

This repository contains CMake modules which are used across Shlomi Fish's projects.

pytmx is a map loader for python/pygame designed for games. It provides smart tile loading with a fast and efficient storage base.

Chipmunk is a simple, lightweight, fast and portable 2D rigid body physics library written in C.

SFML provides a simple interface to the various computer components, to ease the development of games and multimedia applications. It is composed of five modules: system, window, graphics, audio and network.

GrafX2 is a bitmap paint program inspired by the Amiga programs Deluxe Paint and Brilliance. Specializing in 256-color drawing, it includes a very large number of tools and effects that make it particularly suitable for pixel art, game graphics, and generally any detailed graphics painted with a mouse.

Box2D is a 2D rigid body simulation library for games. Programmers can use it in their games to make objects move in realistic ways and make the game world more interactive. From the game engine's point of view, a physics engine is just a system for procedural animation.

Package sdl provides a Driver for making native graphical apps.

Python TMX reads and writes the Tiled TMX format in a simple way. This is useful for map editors or generic level editors, and it's also useful for using a map editor or generic level editor like Tiled to edit your game's levels.

MyGUI is a library for creating Graphical User Interfaces (GUIs) for games and 3D applications. The main goals of MyGUI are: speed, flexibility and ease of use.

ScummC is a set of tools allowing to create SCUMM games from scratch. It is capable of creating games for SCUMM version 6 and partially version 7.

The SGE Game Engine ("SGE", pronounced like "Sage") is a general-purpose 2D game engine. It takes care of several details for you so you can focus on the game itself. This makes more rapid game development possible, and it also makes the SGE easy to learn.

pyscroll is a simple and fast module for animated scrolling maps for your new or existing game.

PLIB is a set of libraries that will permit programmers to write games and other realtime interactive applications that are 100% portable across a wide range of hardware and operating systems. PLIB includes sound effects, music, a complete 3D engine, font rendering, a simple Windowing library, a game scripting language, a GUI, networking, 3D math library and a collection of handy utility functions. All are 100% portable across nearly all modern computing platforms. Each library component is fairly independent of the others

PhysicsFS is a library to provide abstract access to various archives. It is intended for use in video games. For security, no file writing done through the PhysicsFS API can leave a defined write directory. For file reading, a search path with archives and directories is defined, and it becomes a single, transparent hierarchical file system. So archive files can be accessed in the same way as you access files directly on a disk, and it makes it easy to ship a new archive that will override a previous archive on a per-file basis.

Sfxr is a tool for quickly generating simple sound effects. Originally created for use in video game prototypes, it can generate random sounds from presets such as "explosion" or "powerup".

The STEAD (Simple TExt ADventures) interpreter provides functionality to play games that mix elements of visual novels, interactive fiction and classic point-and-click adventures.

QQWing is a Sudoku puzzle generator and solver. It offers the following features:

1. Can solve 1000 puzzles in 1 second and generate 1000 puzzles in 25 seconds.

2. Uses logic. Uses as many solve techniques as possible when solving puzzles rather than guessing.

3. Rates puzzles. Most generators don't give an indication of the difficulty of a Sudoku puzzle. QQwing does.

4. Can print solve instructions for any puzzle.

5. Customizable output style, including a CSV style that is easy to import into a database.
