Haaf's Game Engine - Hardware accelerated 2D game engine. Allegro - Introduction - Allegro 4 and Allegro 5 are cross-platform, libraries mainly aimed at video game and multimedia programming.
They handle common, low-level tasks such as creating windows, accepting user input, loading data, drawing images, playing sounds, etc. and generally abstracting away the underlying platform. However, Allegro is not a game engine: you are free to design and structure your program as you like. According to the Oxford Companion to Music, Allegro is the Italian for «quick, lively, bright».
