10k glitch: Difference between revisions

The '''10k glitch''' is a glitch that exploits how the game physics tries to slow Mario down when Mario is sliding forward and the player tilts the joystick backwards. For example, on a default friction floor type, Mario's speed is multiplied by .92 + (.01+v/10,000)cos(DYaw), where v is the speed units Mario has. DYaw is the difference in angle between where Mario is facing and joystick tilt, thus cos(dyaw) is always negative. The slowing effect is stronger if Mario is faster. If Mario has 9100 speed, he will immediately stop in place. But past that, Mario's speed can be instantly reflected into small backward speed, and once he has more than 20k speed, Mario's speed can even multiply by several factors. At 90k speed, Mario's speed is scaled by -8 into -7200 speed. And at 262k speed, his speed is scaled by -261 into -69.4 million speed.
