Cosmo's Cosmic Adventure: 2 Open Source Clones Compared
Cosmo-Engine is a new SDL2/SDL_mixer-based engine for playing Cosmo's Cosmic Adventure, requiring only a copy of the original game data. Cosmore instead aims for a byte-accurate reconstruction of the original DOS binary using the original 1988-era Borland Turbo C and Turbo Assembler toolchain, reporting 96.30% byte-for-byte accuracy against the original executable, but requires a DOS build environment such as DOSBox rather than compiling natively on modern systems.
