# Alien vs Predator: reconstructing the Atari Jaguar cartridge

> Alien vs Predator reconstructs the 1994 Atari Jaguar game's Motorola 68000 code and cartridge build from source. The build combines reconstructed and exact-fit modules with data extracted locally from the user's World retail image; the author reports a byte-for-byte match of the resulting cartridge.
