# Cosmore: reconstructing Cosmo's Cosmic Adventure

> Cosmore reconstructs the DOS source of Cosmo's Cosmic Adventure 1.20 in C and assembly for its three episodes. It builds with Borland Turbo C and Turbo Assembler and compares executable load images against the originals; the author reports 96.30% byte agreement, with remaining differences attributed to data layout.
