canadianstickdeath | Kirby's Dream Course - "Extra Course" in 36:45 @canadianstickdeath | Uploaded 8 years ago | Updated 10 minutes ago
EDIT 2: Faster run here - youtube.com/watch?v=87Q9xnyCOx0

EDIT: I was hoping to improve this right away, but clearly it's going to be a while before I get around to doing it...

The category's rules don't specifically allow for this, but I did this run from a completed file. The only way to get a fresh Extra Course file is to spend 40 minutes unlocking it -- there's no way I'm doing that before every single attempt! (At least... no way I'm doing that until I'm ready to tackle both Normal and Extra together. And I don't like playing on VC so don't say to use that version and copy saves around. And don't tell me to buy a game saver either, whatever the hell that is. Unless you're buying? I've heard it doesn't actually work for this because it doesn't save SRAM?) The difference between a fresh file and a completed file is that, with a completed file, I have to scroll down to the next course rather than being placed on it automatically. But it does skip some animations. Rough timing suggests the use of a completed file is slower by about 2s. The other difference is that you can't tell whether or not you reset too early at the end of a course until after the run and you check the rankings to see if all the new scores are there. I proved to myself that they all saved, but to prove it to you I'd have to spend 20s scrolling the rankings menu before every single attempt. If I'm not spending 40 minutes then I'm not spending 20s either.

Extra Course is super hard. Many of shots require precise power levels, and there are many things that can go very wrong when things don't go exactly according to plan.

Notable Mistakes:
3-2: Full Power isn't the ideal power to use on the 2nd shot. The window for the B press is sometimes smaller or larger depending on how shot 1 went, but I definitely wanted to press B a lot sooner after the 3rd bounce than I did.
3-7: Too much power on shot 2, so I jumped the divider. It's a bad mistake as it usually takes 2 shots to recover.
4-6: I didn't put enough power on shot 2 and jumped the divider. I reacted in time to stop myself from flying off the cliff, so that's nice, but the recovery goes downhill after that.
5-5: Pushed B too late and so I hit some lag frames and it didn't come out at all. I had to turn around and go back, but luckily I still got everything done I wanted to do on that shot.
5-8: Underpowered the shot and so I didn't get the boost I needed which would have lined up my trajectory perfectly for the next two enemies.
Extra 7: This is by far the hardest course in the game to speedrun. I lost over 30s in this course, most of it on 7-6, and previous best's go of it lost about 10s of its own.
7-2: Sinking right into the hole is hard. Sometimes I get it and sometimes I don't. This run's effort was somewhat feeble.
7-4: Sometimes it goes in on this shot and sometimes it doesn't. Costs me over a second on the next hole too because Kirby complains after the first shot.
7-6: This was the run's biggest mistake, and it was pretty dumb. Apparently I didn't press up before firing the shot, or at least I pressed it too early or not hard enough or something. I basically just flailed around after that. This isn't supposed to be a place where you can lose this much time...
7-7: Had to use the Hi Jump to reach the hole due to some bad power levels and bad boosts. Normally the Tornado is a faster backup, but thanks to the nonsense of 7-6, I didn't have it with me.
A sampling of minor mistakes: After 2-8 (rankings menu - this wouldn't happen with a fresh file), 5-6 (had to resort to using Tornado), and 7-1 (boosted too hard).
