https://www.youtube.com/watch?v=I292_QG4OzQNew Castlevania: Cadence of Agony in the works by myself and a new team (most need to be found.) It will be an actual full on conversion hack along with utilizing the full potential of the MMC5 chip including an actual MMC5 sound engine.
It will be years until it's released so please be patient in it's development!
