Proto:Super Mario Kart/kar4t

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. The changes are unfinished.

Even though it's dated the same, it's a later build than mario-kart. Even more things are finalized, with minor differences left.

To get the ROM working, apply this patch.

Changes Between This Build and thePrevious Build

Features

• The ending is now completely implemented, and proceeds to The Ending screen.
• You can now navigate the menus using Select.
• There's a build-exclusive debug mode for Time Trial. It seems to be for your driver and your ghost:
  • First row: Your character's speed, coordinates and button presses. The top right counts the button presses, and seems to lock at 05E4.
  • Second row: The Ghost's speed, coordinates and button presses. It seems that the last 2 sets remain at 0000.

Gameplay

• The driver's stats are finalized.
• Rainbow Road is updated, but not identical as the final. The track now has the flashing Thwomps.
• The AI is polished compared to the last build.
• Ghost saving is now finalized.
• It's not possible to skip the win animation by pressing Start.

Graphics / UI

• The US's final title screen is implemented.
• Cheep-Cheeps are no longer upside down.

Sound

• The unique sound effect played when using a mushroom and going over a hop or a ramp is now implemented.
• The Boo item SFX's are now implemented.
• The enemy hit sound uses the final's sound effect.
• Koopa Troopa's theme now has the final's piano and percussion sections.

General Differences

• Pressing Start + Select at the title screen crashes the game. In earlier builds, this will load a Debug Menu.
• Attract mode demos are not updated. Like earlier builds, the driver rams into walls, because the inputs haven't been rerecorded to account for track changes.
• On the ending's "Thank you" screen, the symbol on D.K.'s shirt is missing.
• It's still possible to use items while in the flattened state, which could cause bugs.

Sound Differences

Peach's Theme

Proto	Final

Identical to the final, save for the bassline being played by a piano.

Toad's Theme

Proto	Final

Toad's theme plays at final's tempo, but still uses the brass hit samples like those heard in mario-kart.

Other Sound Differences

• The engine noise still throttles down when drifting, like you're letting off the gas.
• Like mario-kart, Rainbow Road's BGM is still not finished. Battle Mode's theme plays instead. It's likely Rainbow Road's music was the last implemented into the game.
• The Ending scene is cut too early, cutting off the last second of the song.
• A slower tempo is still used for Yoshi's Theme, as well as Ghost Valley's music.
