Cave Story has been made officially available on PC (freeware and Plus), Mac (Plus), Nintendo 3DS (Cave Story 3D and eShop), Nintendo DSi (DSi Shop), Nintendo Wii (Wii Shop), and Nintendo Switch (Plus). These versions each have different sets of features, some being exclusive to certain versions. The price also varies for each version. Many unofficial ports have also been made for other systems such as PSP, Xbox, GP2X, and even Sega Genesis.
