Haduken/Shoruken

This isn't hard at all. Go to the second sigma stage. This is exactly like X2's level and has the same capsule in the same place. So if you know where that is you don't need to read on. Ok, go into the level till you see a ladder that is unreachable and spikes to the side of it. Charge up the Shield weapon and jump on the spikes to the ladder. Then go up and when the shield goes out make another one arcoss the many rows of spikes and make sure your at full health, and slide down the far left wall after all the spikes and there will be a capsule w/ dr. light. You must have the all the armor upgrades, sub tanks (may not be full I don't think), all heart tanks, and full health. To do haduken, Charge up and hold down and let go. To do shoruken, charge up and hold up and let go. These are very usefull.
