Ninth Capsule
There is a secret Dr. Light capsule in the game which gives you the Hadoken and Shoryuken. It is on the third Sigma stage as X, just before you would go and battle with Velcana. There is a long vertical corridor with the rocket platforms you have to climb up (because both sides of the room are electrified). At the very top, Air Dash right through the electric wall into a room with Dr. Light. He will give you the Hadoken and Shoryuken. To use them, charge up the X-Buster to maximum. Then, press [Up] + [A] to do the Shoryuken and [Down] + [A] to do the Hadoken.

Extra lives
Use the following trick to easily get the maximum number of lives, nine, with Zero or when playing in Xtreme mode. Go to Zero's first level. Near the beginning there is a part where you have to ride on a platform. Instead of getting on the one that goes to the right, get on the one that goes up. There will be an area there that has an extra life. Collect the extra life then exit the level. Note: You must have already completed the level on order to exit. Then, return and repeat until you have nine lives.
Get Laser Enhancer for X without getting his head part
If you want to get everything but the head part for X (you do not need to get the head part), you need to have the machine which enables you to switch between X and Zero. With X, jump, then jump again on the side of the blocks that break. While you are on the side still jumping, switch to Zero. Zero must have his head part in order for this to work. Start jumping and crushing the blocks with Zero, then change to X and get the Arm Enhancer.. This useful because when you get fourth armor, you can only hold two parts. However, if you have every piece of armor except the head, you can still hold four parts. The head is only useful for getting the arm enhancer. It is much easier to defeat Bosses holding four parts.
