A prototype for the US localized version of the Super Nintendo Entertainment System launch title Super Mario World has become available to play courtesy of video game preservation Website Forest of Illusion. As originally reported by My Nintendo News, the never-before-released version of the 1990 action-platformer became available to the public via the site on December 24.
According to information provided on Forest of Illusion's Website, the prototype build predates the official North American release date of Super Marion World by 10 months, carrying a date of October 25, 1990. The game first hit store shelves in Nintendo's native Japan on November 21, 1990.
The Website indicates that there are "quite a few notable differences within the game’s dialogue and graphics, with even some additional debugging features being present." Some of the changes are quite subtle, such as a different style to the lettering on the sign in front of Yoshi's house and the text box being slimmer in general than in the version that hit store shelves, while others are more significant, like test stages that are accessible through Star Road and Mario not dying upon the timer running out.
Linking the game to another classic SNES title, the prototype build also includes font graphics that match those included in an early version of The Legend of Zelda: A Link to the Past. Additionally, Forest of Illusion's site states that ghostlike enemies Boo Buddies and Big Boo instead have the pun-laden names Boo Diddly and Boo Jackson, respectively.
"Being a localization prototype, many debugging options are available, making going through the game a breeze!" the description states. "You’ll instantly notice that Mario is able to walk to any point of the map without completing the previous stage."
Additionally if you want to complete a stage without actually finishing it, you can simply press both the select and start buttons simultaneously. Holding up while pressing select will cycle through Mario's various powered-up states, and while in cape mode, different button presses can cause Mario to either fly without limits or simply move anywhere on the screen. Finally, there are options to replay or skip to different cutscenes.
