Scrooge McDuck is advanced in years, he travels around the lake with Niagara on one side and Scotland on another, and beats money out of half-transparent bosses. He hides in the sand and rides the vertex, gets lightning strikes and beats liquid D-1000 robot with his little toe. He also jumps on his pogo stick like he has dementia. Or maybe all that is just a fancy of his senile mind?

The authors, feos and MESHUGGAH, complete the game 3.66 seconds faster than the previous movie by adelikat by minimizing lag, general optimization and some new tricks.

This movie does not get the best (100%) ending, but also does not get the worst (no money).

Total movies: 4

A new TAS of Duck Tales 2. This joint work of adelikat and Guybrush is about 10 seconds faster than the previous version by Genisto.

Quote from Exim (the author of the first Duck Tales 2 TAS):
This one has the "bad" end. (not the worst)
There are 3 endings: no money earned; earned some money and found all 7 map pieces. I'm thinking about doing the best end but I don't know if this would be interesting because I'd have to visit some places twice and it would be a lot longer.

In Duck Tales 2, you control a duck who can use his cane as a pogo stick. He and his family (the NPCs that this run does not talk to except once when forced) search for hidden treasures around the world.

The author, adelikat, completes this game a little more than 5 seconds faster than the previous movie by himself and Brushy. The biggest time-saver was skipping a cutscene in level 1. Expect a lot of pogo action, jumping from ropes and hooks and across spikes unharmed, and quick beatdown of bosses.

This movie does not get the best (100%) ending, but also does not get the worst (no money).

This is Genisto's TAS movie of Duck Tales 2, 41 seconds faster than the previous version by Exim.

Quote from Exim (for his movie, but applies to this one as well):

There are 3 endings: no money earned; earned some money and found all 7 map pieces. I'm thinking about doing the best end but I don't know if this would be interesting because I'd have to visit some places twice and it would be a lot longer.

This is a historic movie, submitted and obsoleted before the creation of the database-based (and wiki-based) site engine, before July 2004.

It was inserted to the database in a history revival project by Bisqwit in autumn 2006.

Quote from Exim (for his movie, but applies to this one as well):
This one has the "bad" end. (not the worst)
There are 3 endings: no money earned; earned some money and found all 7 map pieces. I'm thinking about doing the best end but I don't know if this would be interesting because I'd have to visit some places twice and it would be a lot longer.

This movie plays on hardest difficulty and does a fairly good job and being speedy.

Applied jy's amazing solutions in level 4:
  • Jumping through the destroyed block faster
  • Grabbing the ring at higher position (to jump on the column faster)

Boss 3 starts at 15501 and spawns at middle.

Barrel is 1 frame slower than guy because it would require to delay a frame to get the same subpos and it would be slower.

Comparison time with time of picking up the flower. My last uploaded movie: 5296 11278 (level 3 first fall lag: 12856) This movie (with feos' level 1): 5286 11268.

Note that this route doesn't takes the "better" Y pos by boosting differently at ~8758 (bird at rope). Taking it would make it 1 frame slower due to lag. I've already got so bad lag frames after the 3 rings around 9332.

Level 3 started with same subposes so it's 1 frame slower than the guy. As far as I see, it's only possible by losing 1 frame and tweak subpos at boss fight 1.

Route for level 1 must be tested more to lose less frames from lag and still have boss patterns:

  1. 2 divings
  2. 1 slow flight down
Flight down being first we need all 2 HP on boss, while if he starts from 2 divings, and finishes with flight down, we save HP and he falls from a lower position.

RNG values that make him do a slow flight (all the rest are for diving):
20-3F, 60-7F, A0-BF, E0-FF

Need a better pattern, maybe MESHUGGAH shaves some in-level frames.

Currently 80 frames over adelikat.

Removed a lag frame from level 3. Boss pattern changed so redid. No HP loss in this level, because it doesn't saves frame anywhere.

52 frames faster than adelikat's published run until start of level 4.

Currently implemented optimizations from me: - optimizing "grapp target" jumping offs - abusing a position/subpixel trick to throw crates as fast as possible (removing 1 frame of direction 16 frames earlier of doing that action) - lag frame removing like a boss (carefully making actions) - pogo stick mania at level 1 after crates instead of ducking - movement optimizing mostly on ropes - different route at 2 places (stone at level 3 and level 3 boss) because of pattern change

Added feos's level 4 part (a bit synced until ~18133, ropes...)

- Jumping off the rope at 2117 - Better catching the grapple target - Maybe better jump to the end of the screen after logs/water scene? - Better catching the grapple target - Second "moving platform" sequence changed (pogo stick madness). Somehow I can throw the next crate much earlier.

Positioning

Regular horizontal moving speed is 1.x pixel per frame. x is subpixel value, each subpixel used in the game is 4 256ths of a pixel, and it alters within 1/2 of a pixel each frame you move (it is either less than 0x80, or more). X subpixel rolls each frame you move, even if you are running into a wall. So by adding such wall bumps when possible you can manipulate X subpos to always result in a higher total position.

Y subpixel only advances while you are on a rope, or are falling through a screen transition gap. So you can manipulate Y subpixel by grabbing the ropes or jumping into gaps at different time. Sometimes Y subpixel is critical for some collision.

Subpixels get carried between levels, so you want to adjust them after boss fights to be higher. X position resets to a default value on each level start, so you will be farther right even if you moved left enough to have 0x80+ subpos.

Collision glitch

You usually are able to damage enemies only from above, but if you position yourself right relatively to an enemy, you can damage them from a side. This requires enemies to move to allow precise adjustment, doesn't work on Boss 1 when he is in the upper corner.

Interactive objects

Usually you need to run into an interactive object to setup hockey hit on it or pulling it. But if you are moving along the same platform before it for 15 frames, you can add one blank frame 16 (or 32) frames back and be able to hit it as soon as you reach it.

Jumping for 4 frames once you press B cancels the rest of hit animation as you land, so you can move forward instantly too.

Zipping

The game has hidden boxes. If you spawn them at a proper position and face backwards for a proper frame, you get zipped through them, gaining about 10 pixels.

RNG

Usual RNG roll:

      $D320:A5 8F     LDA GlobalTmr
      $D322:65 90     ADC RNG
      $D324:85 90     STA RNG
      $D326:E6 90     INC RNG
It runs each time you kill an enemy that can drop an item, or when an enemy wants to get its new pattern. So you can manipulate RNG by killing enemies at different frames. Bosses also account your X position, mixing it with global timer and previous RNG values.

More code samples can be found in DT2 thread.
