The above link is arguably the best guide to the Fatal Fury storyline. I haven't found any mistakes through it and it follows the FF storyline right through to Garou:MotW.

I'm not an expert on the KoF storyline, but from what I know this guide is also accurate.
Both links are from <a href="http://www.gamefaqs.com," target="_blank">www.gamefaqs.com,</a> if they do not work you'll have to find them manually from the gamefaqs website.
