When you have the spider ball, return to the Chozo astronomy lab in Skytown, Elysia. It is at this location that you get into a light up bomb thing as a morph ball, and magnifying lenses move to a position and a probe is sent into the sky that gives you maps. If you enter and use ALL the bomb things one at a time you will have maps for ALL of the planets and positions of upgrades. They will appear as a sphere and when they are acquired they will become an X.
At the 'Bonus Content' option purchase the 'Bumper Sticker' bonus and the stickers that will appear on your ship will be relative to the game saves you have on your Wii hard drive. The following games also have special decals.
If you go into hypermode and have the upgrade Screw Attack, you will be able to inflict massive damage on your enemy or boss. Just press + and then press B, B, B, directly at the enemy or boss to infict devestating power. I did this on the Berserker Lord, and without the shield on his head, I used Hyper Screw Attack and killed him in one hit. This move is practically more powerfull than the Hyper Missle.
