Proto:Super Mario Kart/kart *

This is a sub-page of Proto:Super Mario Kart.

This article is a work in progress. ...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.

To do: Everything Info on debug mode (accessed by pressing Start+Select on the title screen, seems to be similar if not identical to the one found in mario-kart-*)

A later build than mkart, and very similar to the unreleased prototype, though it still has some differences. The ROM has a timestamp of May 18, 1992.

The build is actually split into two files: kart_01 and kart_02. To get the build working, append kart_02 to the end of kart_01 and then correct the header.

General Differences

• The logo is still based on the Japanese version.
• The cup selection screen lacks an orange border as well as showing which cc you've chosen.
• Course Select is misspelt as Course Selct in the course selection screen.
• During the result/score tally screen, the CPU that don't manage to finish in time get an "OUT" instead of their time like the final.
• When having 0 coins, the coin UI doesn't flash like the final.

Gameplay Differences

• Falling into the lava, water, or of the map doesn't give a coin penalty. Oddly enough this is present in the earlier mkart prototype from April 13, 1992.
• Moles do not attach on you; instead, you just spin out.
• You can still lose coins after you've finished and bonk into someone.
• You do not get an extra life after you've finished first three times.
• The CPU appears to not be able to get hit by dropped bananas, as well as items fired by other CPU's. As a result, you never see other CPU players getting hit on the minimap way behind you while playing, unlike the final.

Item Differences

• Lightning does not really cause the AI to slow down.
• Characters made small by Lightning cannot be squished.
• Touching bananas put you on full stop like green shells.
• Going over an obstacle like pipes and Piranha Plants with a star make you feather jump instead of destroying it.
• Bananas can't be thrown forward and shells can't be dropped.

Sound Differences

• Going over a bump with a Mushroom causes no sound. In the final, it causes a higher-pitched bump sound.
• Using Lightning plays no sound.
• Getting stomped by a Thwomp plays a different sound.
• Going the wrong way plays a slightly different Lakitu sound.
• Hitting an enemy with an item plays a slightly lower-pitched sound
• The sound effects of driving on terrain tiles such as the Donut Plain's grass or Bowser's Castle tiles are missing.
• Going over the bridge in Donut Plains plays a slightly different sound
• On the final lap when you are 5th or below a different sound plays, which is different than the one Lakitu plays when going backwards.
• Using a ghost gives a 'proceed menu' sound when you steal an item and a 'go back to previous menu' sound when stealing no item. Likely placeholder sounds.
• Finishing does not give the finished sound. Instead, the victory jingle (or defeat) will immediately start playing, proceeded with the character's victory theme.

Bugs / Issues

• Rainbow Road has the graphics missing for the position counter, thus crashes when the final lap is reached, making it incompletable. This makes completing 100cc currently impossible.
• In Battle Mode, going out of bounds using a feather causes you to become permanently stuck, similar to the undumped prototype. Oddly enough this works completely fine in the earlier prototype from April 13, 1992.
• When Lakitu pulls you over the finish line, the lap won't count.
