Hyperspeed Wall Kicks

Hyper Speed Wall Kicking or HSWK is a glitch that allows Mario to build up speed by repeatedly wall-kicking.

Execution

By wall-kicking against a wall on the first frame possible, you will conserve your speed. This is known as a "firsty". By holding a direction on the joystick when Mario is in the air, he will gain speed. Then you can firsty against another wall and repeat the process. This method usually produces up to 400 speed; after Mario surpasses 400 speed, his intended position will go past the wall. He will therefore either clip through the wall or bonk on out-of-bounds and lose all his speed.

Uses

This is useful for:

• Any% (1 Star) BLJless - to bypass star doors
• PSS Double Star Spawn - to bypass the race-starting triangles
• The Low Doors Challenge - to bypass doors
• The Capless/Cannonless and CCC challenges - to clip into the secret room in Big Boo's Haunt without the Vanish Cap
