Super Mario World Game Secrets: The Unauthorized Edition

This was one of the best-selling video game guidebooks of the 90's. It's a bit odd, in that there were two different versions of this book published (one with this name, the other with the slightly different title of Super Mario World Secrets), and I'm unsure of the reason behind the name change. I have both books, but aside from some minor changes on the Library of Congress page and some slight differences in cover design, I can't tell a difference. This one is copyright 1991, while Super Mario World Secrets is copyright 1992. But they otherwise have exactly the same information, the same page count, the same screenshots and information. They even use the same ISBN. I haven't done a page-by-page, line-by-line comparison on my copies, but if there are any differences, I've been unable to find them.

This is entirely different from the Legend of Zelda: A Link to the Past book from the 'Secrets of the Game' series, where one version contained tips for Link's Awakening on the Game Boy, while the other had strategies for Legend of Zelda and Zelda II on the NES. So while I did scan both versions of that book, I don't see any reason to do so for Super Mario World Secrets unless someone can point out some major differences or discrepancies in the text.

In any case, this is a perfectly awesome walkthrough for the game, even if it's only black and white. It won't help you break a speedrun record or anything like that, but it does actually feature a small section on getting through the game as quickly as possible, using only 13 of the game's stages (or 11 if you're willing to skip the Yellow Switch Palace), which I absolutely used back in the day.

In any case, enjoy!
