DK Bongo Blast was announced for GameCube on May 9, 2006 at the E3 convention for the Nintendo GameCube, but then it was cancelled. On September 14, 2006, the game appeared on a Japanese list from Nintendo of 2007 Wii titles. The game was released only for the Wii. – [info from Wikipedia]
On the 24 November 1995, Nintendo finally presented the final version of the Ultra 64, (renamed “Nintendo 64” because of copyright problem) at the Shoshinkai Software Exhibition. Among the thirty titles shown in playable form or in video (including Star Fox and Wave Race) one of the most interesting was Super Mario Kart R, an early beta version of our favorite kart-game.
Compared to other games that were shown at the Shoshinkai that year, it could be said that Mario Kart R was almost complete, since there appears to be no particular changes in the track design, but the differences for the playable characters are interesting. You can notice that Kami Koopa (Magic Koopa) was a playable character in the game instead of Donkey Kong and the “Character Select” screen had different avatars. Also, the multiplayer split screen could have been set to horizontally or vertically, but this option was removed in the final version (but implemented in Double Dash). The “Item Boxes” were different too and various other little graphic details (like the HUD) were changed before the game was published,
Also, the Feather item from the original Super Mario Kart, was meant to be used in Mario Kart 64 too, as you can see from one of the screenshots in the gallery below (in the image with the 4 player mode, Toad has it in his item HUD). The Feather would have let the player to jump very high, to reach new shortcuts or to avoid obstacles.
