100% completion baby! Well, I spose' you could say it's technically not because I didn't get the best ending due to the slower pacing of a walkthrough. But if you'd like to go for it, go ahead! But keep in mind you won't get any more than a different image through meeting these requirements: http://www.gamefaqs.com/gba/516709-metroid-fusion/cheats
So you aren't missing much by not speed running it, lol!
