An unofficial Castlevania: Symphony of the Night PC port has finally emerged from its crypt, but it's based on the Xbox 360 edition of the game rather than the original.
Recompilation efforts have made a big wave in the industry over the last few years, and so far – a few outliers like Sonic Unleashed and WWE SmackDown vs. Raw 2007 notwithstanding – have mostly focused on the fifth generation of consoles, with most of the all-time N64 classics having brilliant PC versions available right now. Super Mario 64 was the first time I'd heard of it happening, but impressive ports for Banjo Kazooie, Zelda: Ocarina of Time, and Majora's Mask have been big hits among fans.
