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

CSFML is the official C binding to the SFML libraries. 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.

libccd is library for a collision detection between two convex shapes. libccd implements variation on Gilbert–Johnson–Keerthi algorithm plus Expand Polytope Algorithm (EPA) and also implements algorithm Minkowski Portal Refinement (MPR, a.k.a. XenoCollide) as described in Game Programming Gems 7.

BBC BASIC is the programming language originally specified and adopted by the British Broadcasting Corporation for its groundbreaking Computer Literacy Project of the early 1980s. BBC BASIC for SDL 2.0 combines the simplicity of BASIC with the sophistication of a modern structured language, allowing you to write utilities and games, use sound and graphics, perform calculations and create complete applications.

LÖVE is a framework for making 2D games in the Lua programming language.

The Graphics Resource File (GRF) development tools are a set of tools for developing (New)GRFs. It includes a number of smaller programs, each with a specific task:

1. grfcodec decodes and encodes GRF files for OpenTTD.

2. grfid extracts the so-called "GRF ID" from a GRF.

3. grfstrip strips all sprites from a GRF.

4. nforenum checks NFO code for errors, making corrections when necessary.

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.

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.

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.

Pygame_SDL2 reimplements the Pygame API using SDL2, staying close to the original, but also adding some SDL2-specific features. While it aims to be used as a drop-in replacement, it appears to be developed mainly for Ren'py.

LÖVE is a Lua framework for making 2D games. Nuklear is a minimal state immediate mode graphical user interface toolkit. This package is the Nuklear bindings for LÖVE created by Kevin Harrison.

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

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.

This package provides a game networking framework for Python.

Pyxel is a game engine inspired by retro gaming consoles. It has a fixed 16-color palette, can hold up to 3 image banks and 8 tilemaps (256x256 pixels each) and 4 sound channels with 64 definable sounds. It also comes with a built-in image and sound editor.

DeuTex is a wad composer for Doom, Heretic, Hexen and Strife. It can be used to extract the lumps of a wad and save them as individual files. Conversely, it can also build a wad from separate files. When extracting a lump to a file, it does not just copy the raw data, it converts it to an appropriate format (such as PPM for graphics, Sun audio for samples, etc.). Conversely, when it reads files for inclusion in pwads, it does the necessary conversions (for example, from PPM to Doom picture format). In addition, DeuTex has functions such as merging wads, etc.

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.

ODE is a high performance library for simulating rigid body dynamics. It is fully featured, stable, mature and platform independent with an easy to use C/C++ API. It has advanced joint types and integrated collision detection with friction. ODE is useful for simulating vehicles, objects in virtual reality environments and virtual creatures. It is currently used in many computer games, 3D authoring tools and simulation tools.

NewGRF Meta Language (NML) is a python-based compiler, capable of compiling NML files (along with their associated language, sound and graphic files) into .grf and/or .nfo files.

Tsukundere is a game engine geared heavily towards the development of visual novels, written on top of Guile-SDL2. It is still experimental.

SLADE3 is a modern editor for Doom-engine based games and source ports. It has the ability to view, modify, and write many different game- specific formats, and even convert between some of them, or from/to other generic formats such as PNG.

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.

libtcod is a fast, portable and uncomplicated API for roguelike developers providing an advanced true color console, input, and lots of other utilities frequently used in roguelikes.
