Fast move：

Ryu's moving speed can be controlled by pressing left/right, I or II button.We can achieve a faster speed than usual walk or jump by pressing Left/Right+I or II button alternately.

Fast ninpo release:

This bug is first applied to boss fight in t1280136161's test TAS.At the second last frame Ryu draws back his hand in one ninpo release cycle,he can release another ninpo without cancelling the rest action and preparatory action if following condition is satisfied ninpo is throwing star or the effect of released ninpo is eliminated.If the condition is satisfied always,Ryu can release his ninpo every two frames.Especially, fot the case ninpo is throwing star,because only five throwing stars are allowed in one screen,this tech would lead to game glitch or some useful bugs,one of them, warp bug,is the key to this run.

Warp bug:
