# Kirpich: reimplementing Game Boy Tetris behavior

> Kirpich recreates the Game Boy Tetris game in native C++ on Polyrhythm using behavior specifications derived from the original. It reads graphics and sound from the player's ROM and runs the original randomization and sound routines in a narrow SM83 virtual-machine host; desktop builds add optional modes and controls.
