Ancient - Ancient's website. It's mostly in Japanese although there is an English section (with some bizarre translations). The best thing about the site has to be the fact that Yuzo Koshiro posts on their message board quite frequently, so if have any questions for the electronic musical maestro it's the perfect place to visit.
Blaze Fanart - Japanese site that has a section for Bare Knuckle with some 'interesting' Blaze fanart. Check out:
Alisia Dragoon - My tribute site to the little-known Genesis/Megadrive fantasy platformer/shoot'em up.
Castlevania Dungeon - Nice Castlevania site with tons of content - a must visit for fans of the series.
ClassicGaming.com - The kind hosts of this website and a must visit for anyone interested in classic video games.
Death Adder's Castle - A cool Golden Axe site, that features everything you can imagine to do with the classic hack 'n' slash series.
Final Fight Online - Great site dedicated to Capcom's fighting classic, as well other titles featuring characters.
GameFAQs.com - The best site there is for cheats, guides and walkthroughs for games on any platform.
Gunstar Heroes - Great website devoted to the classic Genesis/Megadrive shooter from Treasure.
Home of the Underdogs - Site dedicated to the underdogs of gaming; the games that never got the respect they deserved. They have a huge database of free downloads of abandonware (games no longer sold by their publishers).
