It's not so much that it was based on code for Chess. Rather, it was based on code that had been adapted to handle en passant for initial pawn moves that are longer than two spaces. Since this game allows pawns unlimited double-moves instead, en passant had to be handled differently. Either way of handling en passant is compatible with Chess, but en passant has to be handled differently in Omega Chess than in Metamachy.
