List of Mario Kart DS pre-release and unused content

These are beta elements from Mario Kart DS.

Beta Elements
This game's Retro Grand Prix was going to include a few more tracks, such as Mario Circuit (old_mario_gc) from Mario Kart: Double Dash!!(Dismantled for the new Mario Circuit), and Mario Kart: Double Dash!! ' s Block City (mini_block_course) battle area. There was also an mysterious stage with no textures (dokan_course) and SNES Mario Circuit music, as well as a simple, circular test area smaller than even Baby Park; the latter one was a debugging stage not planned for inclusion in the final game. There was also a beach course (nokonoko_course) which most people think is Koopa Troopa Beach from MK64 but it is not. It is likely that it would have been called Koopa Troopa Beach though because NokoNoko means Koopa Troopa in Japanese. These areas can still be accessed using Action Replay DS. Waluigi Pinball was also slightly different (mostly in texture and music, the latter of which was strangely from Yoshi Falls, and the slot machine seen near the end of the lap was part of the course for players to drive over.) in betas, albeit probably a programming error. There was also a track with a similar layout to Waluigi Pinball Beta (pinball_course) with textures from the Tart Top battle arena on the floor and bumpers etc (luigi_course). Demo copies of the game actually showed it with quite a few object differences (such as more bumpers and a less direct launch towards the beginning). The demo version also depicted DK Pass with (perhaps more thematic for its eponymous character) a grassland theme rather than a snow one, with a lone Thwomp near the finish line, as well as many other small differences mostly regarding walls and jumps. The filename of this track is donkey_course but the real DK Pass is called snow_course. There was a beta version of Wario Stadium called wario_course which was exactly the same but missing fireballs and crowd cheering. The real Wario Stadium is called stadium_course. Finally, the last beta course is test1_course whose map is the same as Rainbow Road but contains other objects such as the bridge from Delfino Square and the gears from Tick-Tock Clock. There is also a mysterious "test_brock" which is basically a 3D checkered thing. Finally, demo version guides released for stores by Nintendo depicted the Chain Chomp (which could not actually be retrieved in the demo version itself) as an item; it is presumed that this Chomp munition would work in a manner similar to that of the Chain Chomps in Mario Kart: Double Dash!!, making it likely that Chain Chomps were removed from the game in favor of Bullet Bills (although the listing of the Chain Chomp in these beta guides may have been a simple mistake, though this is unlikely).
