KSS:Rules

Main Category Rules

Any%

In any%, players compete to beat Milky Way Wishes as fast as possible.
Timing begins when a file is selected, and ends on the final hit of Marx.
The only sub-games that need to be cleared to beat the game are Dyna Blade, Great Cave Offensive, Revenge of Meta Knight, and Milky Way Wishes.

100%

In 100%, players compete to beat the game to 100% completion as fast as possible.
Runners are encouraged to show the file select screen to prove 100% completion at the end of the speedrun.
Timing begins when a file is selected, and ends when the "Winner" text stops scrolling once The Arena is completed.

Other Category Rules

The Arena

Players compete for the fastest completion time in The Arena, based on the time given by the game once The Arena is won.
RNG manipulation is possible in The Arena, with most setups for manipulation being done before the run starts.

Individual Level Speedruns

Speedruns for the individual sub-games can be performed.
They are not as popular as full-game speedruns.
There are no specific regulations for TASes, as IL runs are disallowed on TASVideos.org.

Category Extensions

Speedruns that are not meant to be taken as competitively as the main board.
Majority are meant to be funny and are not taken seriously.
Category Extensions include:

• 2 Player - Allows the use of a second controller.
• Softlock% - Softlock the game as quickly as possible.
• Low% - Beat the game with the lowest file percentage possible.

About the Rules

Game Resets

In full-game speedruns, there are some points in the game where performing a soft reset can skip cutscenes to save time (such as after defeating Dyna Blade, or during the credits in 100%).
As of November 8th, 2022, resetting the game to save time is allowed, as runs before this date were not allowed to reset.

• On Speedrun.com, this is indicated by the "Resets" column. A run labeled "Yes" implies that the run uses soft-resetting.
• 100% runs were split between two categories before this leaderboard change ("Resets Allowed" and "No Reset"), due to many runners finding it odd to need to watch the entire credits sequence.
• Both 100% categories were combined into one single category after the rule change.

2 Player, Simultaneous Up + Down / Left + Right inputs

In RTA speedruns, 2 player and simultaneous D-pad inputs are prohibited on the main board.
2 player categories exist on the category extension leaderboard.
Simultaneous D-pad inputs have been used in RTA runs, but does not have a leaderboard. Performing on real console can be done through controller modification, but playing on emulator with a keyboard is ideal.
For more information, see Simultaneous D-Pad Input Bug.
In TAS runs, unless otherwise specified, 2 player and simultaneous D-pad inputs are allowed.
