I'll put down some of my most helpful and favorite websites for you guys to look at!

Ah, I can't figure out how these controls work...

www.fanfiction.net

http://www.sonicteam.com/sonic2b/en/index.html#contents (the ultimate SA2B site!)

www.gamefaqs.com (where you can find walkthroughs for ANY game)

Maybe more later.
