This is a guidebook for the Super Famicom (Super Nintendo Entertainment System) version of Final Fight 1. It consists mainly of game strategy and has some artwork of the characters and one page of story. The bosses are only depicted in black & white. Also Guy and Rolento are not in the SF/SNES version of the game so you won't find anything about them in this book. It has a nice front art of Haggar, Cody and the Mad Gear Gang.
This one is about 2cm larger than the other FF guidebooks and is completely in color. It has artwork of nearly all characters but it's quite blurry especially the art of the non-boss enemies. It has detailed information on how to beat the game but you have to be able to read Japanese in order to understand all of it. The book also has stats for all listed enemies.
This is a guidebook for Mighty Final Fight for the NES (Nintendo Entertainment System). It's full of funny illustrations and has lot's of info for each level of the game. The first page tells the story (game intro), the last two pages are nonsence like in the Capcom Secret Files.
