# Olduvai: reconstructing the Prehistorik engine

> Olduvai reimplements the 1991 Prehistorik engine in C++ and SDL2 for desktop and Linux handhelds, reading data from a user's game copy. Its documented method studies the DOS executable with disassemblers and checks behavior against a separate reference implementation frame by frame; the author reports a playable release candidate.
