Okay, I'm missing one power-up, and it's the one that's right in front of you the whole time!
It's the missile upgrade that's in the hangar... but when I go into the alternate corridor to get to the area where it's supposed to be, the door that leads into the hangar is locked (blinking orange).
I don't get it, I even tried accessing it when you're running back to the hangar after the self destruct sequence is initiated, but that won't work... 
EDIT: Woo! 100%
I am done with Metroid Other M. Solid game marred by some silly design choices: 83/100
