CD-iOverview
Super Mario's Wacky Worlds was intended by Philips to be another game in their line of CD-i titles based on the Mario and Legend of Zelda licenses such as Hotel Mario and Link: The Faces of Evil. Philips had the contractual permission to produce these games for their console outside of Nintendo's supervision following the cancellation of a Philips-developed CD-ROM add-on for the SNES. Unlike Hotel Mario and the Zelda titles, however, Super Mario's Wacky Worlds was never finished and never saw release. A pre-alpha ROM has leaked into the public, giving a faint glimpse into what the game was intended to be before production stopped.
The game was designed as a platformer similar in nature to Super Mario World. The Mario sprite art and the music in the leaked build were both taken directly from the SNES launch title. The game boots directly to a debug stage select menu, allowing the player to in theory select any stage in the game. However, all of the game's stages exist in varying incomplete states; some are relatively playable, but lack an end goal, while others can't be started at all. The build is also riddled with glitches ranging from allowing Mario to go outside of environmental boundaries to becoming stuck and unresponsive to controller input.
