This is mostly for moozooh, since I doubt he has gotten to this point in his low% run yet. This is a method of continuous walljumping in the old mother brain room. It saves at least 6 frames over the traditional method, maybe more. Unfortunately I am too far past this point to implement it into my new any% run, unless I manage to hex it in without a desync. This isn't like a regular continuous walljump because it requires that you press the X, L, or R button after the walljump to continue Samus' momentum and still land as early as possible on the next platform.

Pretty soon I will post a package of little tech demos that I have collected. Most of them are tiny improvements to JXQ's 100% route, but maybe they can be useful elsewhere too.
