WFIRE is a low-level gameengine which provides a portable library allowing for writing video games for multiple classic targets. Originally written for a game called the Crypts of Eldor, WFIRE aims to provide compatibility with a number of constrained environments, such as DOS and the Amiga. It also aims for "new-retro" computers such as the Commander X16 and the Neon816.
Snack combines a high-level object oriented language (think JavaScript) with a bytecode execution engine. An example air traffic control game (a port of the classic ATC) and a text adventure framework are included.
