Metroid Fusion - Weird Glitch On Main Boss (Requires Gameshark)

I try to avoid posting things which require a product other than the game to try it, but I thought this one was worth posting anyway.

Use the "Equip Weapons/Armor" and the "Remove Weapons/Armor" cheats, they should be already on the gameshark.

Now you will need to beat to the point where the Omega Metroid appears, now hold L+B to equip all weapons and armor. You can't hurt it now, even though you should be able to. Just let it hit you until your health gets low, (It will take more than one swing now) and then the SA-x will appear, but you won't be stuck on the ground. You can walk around and even weirder the SA-x shoots towards the left of the screen instead of the right.
