KA:Major glitches

Stone Glitch

This glitch is triggered when the stone ability is activated underwater. Because stone cannot be used when Kirby is in a swimming state, in most cases, it requires going out of bounds. As an exception, this glitch can be activated in the mid-boss room in 6-1 by breaking the block under the door, then mashing B as Kirby splashes in and out of the water. The memory is destroyed and all sorts of weird things happen. In Any%, this glitch is used in conjunction with a frame-perfect pause to warp to the staff credits. On the Nintendo Classic Mini and Switch, doing this glitch will cause an error and force the game to close.

Permanent Copy Ability Glitch (UFO Glitch)

This glitch that is triggered by taking damage or pausing and exiting the stage at the same time the copy ability is discarded. When this is used with UFO, it is possible to carry over UFO that cannot be carried over to other stages in normal play. In addition, the copy ability will not be removed even if damage is taken. This can be done with a sword, hammer, or parasol, and in the case of a parasol, only the fluffy fall will not be possible. When done in other abilities, it becomes a mysterious ability that produces a splash, no practical use.

Damage Carryover

Discard copy ability on select button as soon as damage is taken. Frame-perfect trick. If it is early, the sound of the copy ability release will sound, and if it is late, the sound of the damage taken will sound, which can be used as a reference for timing.

Pause Carryover

Press Start and Select at exactly the same frame and exit the stage at the pause screen. If you successfully press Start and Select at exactly the same frame, Kirby's appearance does not change, even though the ability star you discarded just before the pause screen appears a little above Kirby's head.

Success Pattern

Failure Pattern: early Start

Failure Pattern: early Select

Warpstar Carryover

Discard copy ability as soon as you get on the Warpstar. Frame-perfect trick. The practicality is subtle because it can only be done where there is a Warpstar and the ability disappears if it is done too early.

Collision Pause Glitch

If you pause at the moment an enemy enters the screen, the enemy will move during the pause. This is a frame-perfect trick. If Kirby takes damage in this state, he will be able to move in the pause screen. While paused, the terrain determination is different from before the pause and refers to a specific location within that map. Therefore, while in this pseudo-paused state, a wall can be passed through, or conversely, a wall can be created where there is none. The terrain during the pause is moving as shown in the image in the link below, and the spikes and doors are moving in the same way (Kirby can still take damage from spikes and doors can still be entered during the pause).
