# Cosmo: a native port of Cosmo's Cosmic Adventure

> Cosmo ports the reconstructed source of Cosmo's Cosmic Adventure: Forbidden Planet to macOS, Linux and Windows. It retains the game's logic and supplies an emulated EGA adapter, timer, keyboard controller, PC speaker and AdLib layer for the original code. The build uses the user's game data files.
