  • 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)
