Fatal Fury HELP!

Could someone tell me the diffrence between Fatal Fury and Fatal fury Special?

Fatal Fury is the one that started it all, only 3 players are available to choose from Joe, Terry and Andy. Fatal Fury Special came after Fatal Fury 2 and is a update with more characters. I believe there was like 15 regular and Ryo from Art of Fighting was a hidden guy who you can only get by beating the game without losing a single round. Thank god I had a memory card and saved after every match wink . So Fatal Fury special came two fatal furies after the 1st to answer your question.
