This is the speedrun of Donkey Kong Country in 7:24.68. This is 25.39s(1526F) faster than the previous run (#5074: Tompa's SNES Donkey Kong Country in 07:50.08).

Game objectives

  • BizHawk-2.3.2
  • Uses warps.
  • Aims for fastest time.
  • Takes damage to save time.
  • Uses death to save time.
  • Abuses programming errors in the game.

New Glitch

Instant split-up setup
For split-up, it is nessecary to exit a current level after one Kong releases DK barrel and before it breaks. If Kong with DK barrel stomps on a enemy, he releases DK barrel and it breaks on the ground. But if DK barrel touches the ground when it is released, it doesn't break and rolls. And, Kong usually cannot catch up with released barrel that moves fast. But if he is acceralated by corner boost, he can do. If you use those techiniques, Kong can catch up and pick up rollong DK barrel. This is seen in Tompa's movie (https://www.youtube.com/watch?v=48KGrI59pM8). This is used in 1-1.
Split-up Warp
After split-up setup, Kong enters a bonus barrel with throwing a DK barrel. If this glitch succeeds, current stage is over. (not complete because pause+select exit isn't enable) This is used in 6-5. (Split-up setup is in 6-2.)

Level Summary

Jungle Hijinx:

1+14+276=291F is saved.
1F is saved by avoiding 2F hit stop by not touching Kritters. This is seen in speedruns (https://www.speedrun.com/dkc/full_game)
14F is saved by 2 enemies rollong.
276F is saved by Instant split-up setup. In previous TAS, Start & Select exit is used in stead of Instant split-up setup. As Start & Select exit is doable only in completed level, 1-1 is entered twice in previous TAS. But 1-1 is entered once in this TAS, I can do a split-up without reenter of 1-1.

Ropey Rampage & Orang-utan Gang:

Not improved. Same as the previous TAS.

Manic Mincers:

1F (not lag frame) is saved. If Kong jumps with Expresso just before they reach top speed, they will get to full speed quicker. This saves 18 subpixels. And a corner-boosted jump is made higher. Higher jump extends corner-boosting time. These factors results in 1F saving.

Misty Mine:

Not improved. Same as the previous TAS.

End of Misty Mine to Platform Perils:

1129F is saved thanks to Split-up warp with Tonkotsu route. Two routes is considered about Split-up warp.
1. Tonkotsu route: Split-up setup before Loopy Lights, no SJR in Loopy Lights (The fastest Split-up setup is in Manic Mincers. If the setup in Manic Mincers, SJR can not be used in Loopy Lights because softlock occurs while SJR setup.)
2. Eazinn route: SJR in Loopy Lights, Split-up setup after Loopy Lights
I research two routes, get the result Tonkotsu route is 80F faster than Eazinn route.
(About Platform Perils, Tompa found lag count is changed by holding Down shortly after Donkey started to fall when Diddy entered the bonus. But lag count in this run is increased by holding Down shortly)

Necky's Revenge:

22+10F is saved.
Donkey dance is 22F shorter than Diddy dance. (Diddy was a player character in the previous TAS.)
Donkey can slap at the beginning and avoid DK barrel in Necky's battle. If one Kong after Necky's battle, 10F is saved in moving on world map. So DK barrel is broken in the next last battle. (Necky's battle in the previous TAS.)

Gang-Plank Galleon:

8+12=20F is saved.
If Kong stomps on the boss in the lower position, fake KREDITS starts earlier. This run is 8F faster than the previous TAS.
The last input is earlier thanks to jumping Slap Slide. This run is 12F faster than the previous TAS. (Diddy is a player character in the previous TAS. He isn't able to slap)

I've been struggling a lot at the bonus entrance for 6-5... Here's one method that enters the barrel a frame later but gets a lot less lag, overall one frame faster: http://tasvideos.org/userfiles/info/61083356287213705 I've also had a few variations where I enter the barrel a frame earlier, but got more lag frames. Going to do a couple of more attempts at this tomorrow. See if you have any luck with it as well.

I can save 1F in 6-5 without delay to enter bonus like your bk2. http://tasvideos.org/userfiles/info/61094829542743439

I struggled a lot t osave additional time in 6-5, I couldn't... And while I did save a lag frame against Master Necky, it ended up being slower against KKR because of extra lag frames there. I'm satisfied with this for now, unless you have further improvements. Nice work on this, Hidaigai!

I restored it.
Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

http://tasvideos.org/diff.exe?page=6599S&rev=9&prev=8 Maru's text of resetting the submission back to "new" (at the bottom) was (presumably accidentally) removed, by the way.

I just did a minor change to the submission text. You save 10 frames from only having one Kong on the map screen when entering KKR. The other 3 frames were saved from less lag during the Master Necky fight. All good!

>Maru Sorry. I removed your text (and your action). >Tompa Less lag? This Necky's battle (BizHawk 2.3.2) has more lags than previous battle (BizHawk 1.11.5). What is 13F of your comment in 2020-01-31 02:34:52?

It was less lag compared to your previous version, even if it is more lag than my old run.

I see. I misunderstood 13F was about a comparison to your old TAS. This submission text should be about a comparison to your old TAS. And I omit information about lags because different emu is used. (In Necky's battle with same BizHawk 2.3.2, One Kong play has 7 lags, Two Kongs play has 5 lags. If 'One Kong' were a factor of lag reduction, I wouldn't omit this.) So I will update this submission text from this aspect.
