Getting Zero’s Buster:
To get Zero’s Buster, get all upgrades for Megaman, except for the arm upgrade. Continue playing until you fight Vile the second time in Sigma Palace 3. Defeat him but make sure you do not have the arm upgrade. After defeating him, you will automatically get Zero’s Buster from him.
Once you have all tanks and life expansions with Megaman, enter the Armored Armadillo level five times until the end. On the fifth time, when you are in the cart that jumps and leads to the Boss door, jump to the ledge. You will find a capsule with Doctor Light and the Hadouken Street Fighter style. Alternately, go through the Armored Armadillo level without getting hit once. At the very end when the cart is flying through the air, dash jump to a ledge when the cart starts to descend slightly. There should be a Doctor Light capsule there, and he will give you the Hadouken attack. Note – In order to use this attack you must have full health. Also, roll forward as if you were using it in Street Fighter 2. This move can kill anything with one blast.
Easy lives in Armored Armadillo level:
At the beginning of the level jump on, then off, the trolley-like object as fast as possible and run down the path. There should be structures coming out of the ceiling when you reach the bottom. The first has a mechanical bat enemy and the second one has bat-like enemy that looks realistic. Make sure you also kill the flamingo enemy. When you kill the realistic bat, almost every time it dies it will drop an extra life. Run back to where the second structure on the ceiling is off screen, then run back and kill it again. Keep repeating this process to get as many lives as desired.
Defeating Sigma’s first form:
Use the purple Charge Chameleon Sting, then use the Electric Spark attack (charged or not). To dodge his slash, jump up the wall. When he shoots, jump up the wall and try dodging bullets like that. When Sigma jumps up the wall from you, fall when he is on the other side of the wall. Repeat the Charge Chameleon and the Electric Spark attack until Sigma has been defeated.
Find the following armor in the corresponding locations:
Body Capsule – In Storm Eagle’s level, beyond blocks that must be broken with the Head Upgrade. It is after the thin tower that you climb.
Buster Capsule – In Sting Chameleon’s level, after climbing up a cliff at the beginning of the level, just destroy the green robot. Note – The Dash Upgrade is needed.
Head Capsule – In Chill Penguin’s level, beyond blocks that must be kicked by using the Leg Upgrade. The blocks are found on the right side of a wall in the base.
Leg Capsule – In Flame Mammoth’s level, in a small room which can be accessed by jumping up the left side of a wall after falling through the first long fall.
