Code for the 9th Chip:
In the first stage in Dr. Doppler's lab go to the part where the spike balls are and go down the first hole until you come into a secret place and there will be a Dr. Light capsule there. Go in it and you will recieve all the enhancement to all the parts! *Note: To get this you must have all the weapons, riding armors and heart tanks!

Golden Armor:
You must have all the sub tanks, hearts, and armor. Don't get the four enhancers, as the golden armor will grant you these. When you have everything you need, go to Doppler's first stage and get the first super armor. Move to where the spikes fall into the first pit, then keep sliding to the left until you enter a secret room. Inside will be a pink capsule. Jump on it to gain the golden armor. Note: You have to make it to the secret place with full life.

Super Adaptions:
After killing the mid-boss in the first Dr. Doppler stage, go to the first pit you see. Now slide along the left wall until you go through it. If you have all of thee-tanks, weapons, hearts, and full energy you'll find a capsule that will grant you the four Super Adaptions.
