Since the site's engine isn't configured to handle submissions such as this one, I'll make it a "fake" submission and post it here.
I chose the GBA port of this game over the original NES Kirby's Adventure because I used to speedrun this on my GBA all the time, and I was interested in seeing the theoretical speed limit from running it tool-assisted. My best time was around 4:55, but here, I get an astounding time of 3:25.
The movie starts from a savestate because it
plays an unlockable minigame which would otherwise be impossible to record a movie of. I found a SRAM file on Zophar's Domain (It can be found
here), loaded it into VBA, took a savestate on frame 0, and began recording from there.
The object of this minigame is to defeat the 9 bosses of Kirby: Nightmare in Dreamland, all in a row, with only 6 hit points. You can't get any powers except for those available in the boss stages, and if you beat a boss with a power, you can carry that power over to the next stage.
I believe it's almost as fast as possible, though it looks like I may be able to squeeze an extra 5 seconds or so through better luck manipulation.
What do you think?
