Castlevania: Symphony of the Night is regarded as the peak of Konami’s legendary series, and has a devoted fandom. There have been projects to unofficially port to the Sega Genesis / Mega Drive starting in 2024, but that is not the only project in the works.
Modder Kaffeeware is at a very early stage in the development of an SNES port of the game. There is a long way to go but it’s already looking pretty impressive, and this will no doubt spark debates over which version will be better, Genesis or SNES.
You can see some footage below of the progress made so far.
