# Rondorecomp: a partial static recompilation of Castlevania: Rondo of Blood

> Rondorecomp translates Castlevania: Rondo of Blood’s PC Engine CD HuC6280 code into C at build time and runs it against C models of the console’s CPU, video, CD, input, and System Card services. Its analysis directory contains boot-chain disassembly and tools for code discovery and data decoding. The author reports rendering the intro and file-select screens and reaching the prologue, with much of the game still unverified.
