In 1994, shortly after the Super Game Boy release, Nintendo sent the Nintendo Power magazine subscribers the "Super Game Boy Player's Guide", a 72 page instruction book / guide to using the features of the Super Game Boy. These features gave detail about proper and improper usage of graffiti mode (examples of when it is/is not appropriate to allow drawing over the playable area of the screen), and examples of how color palette changes can make game play eye straining (getting light/dark colors reversed or out of order such as 1324 or 4321 instead of 1234), or duplicating a color as a way of deleting it from the palette (1134 or 1214 or even 1221 and 1114 layouts). The first 15 pages were instructional, followed by 55 pages of very brief overview style walkthrough of several games. These walkthroughs highlighted various points of the games and often pointed out color schemes to set that area's intended mood. (Games included: Super Mario Land 1-3, the new released Donkey Kong which had a special "Super Game Boy" border and color palette, Metroid 2, The Legend of Zelda: Link's Awakening, Kirby's Dream Land and Kirby's Pinball Land, Tennis, World Cup, Alleyway, Dr. Mario, Yoshi, and Tetris.)
