About the Run

  • This is an improved version of My TAS. 4116Frames was saved.

Improvement Points

  1. Route Change
  2. Optimize attack method
  3. Optimization of Speed Up chanting method

Root Difference from Previous

  • Clear Order
Order Boss Name previous order
1 Behemoth 14
2 Keremet 1
3 Mummy Man 2
4 The Creature 3
5 Werewolf 4
6 Medusa 5
7 Brauner 6
8 Dullahan 7
9 Stella 10
10 Death 11
11 Dagon 12
12 Legion 9
13 Nest of Evil Bosses 13
14 Astarte 8
15 Stella & Loretta 15
16 Whip's Memory 16
17 Dracura & Death 17
18 True Dracula 18

  1. First knock down Behemoth because routes out of bound and routes to Behemoth room almost overlap. This allows you to reduce suspend once, so you don't have to move to the Behemoth room for that. Improved over 1000 Frames.
  2. Speed Up knock down keremet before getting. This is about 120 Frames faster.
  3. Don't get Owl Marph with Dark Academy.This is because Push Cube and Strength Glove become unnecessary and it is no longer necessary to precede Sandy Grave.
  4. Don't use the route suspended by City of Haze. This is because Push Cube is no longer needed. But for this you cann't get Moonwalkers. This is affected especially by Nest of Evil, but it is early to compare.
  5. I will postpone Sandy Grave as described above. This is because it became possible to use Toad Morph to acquire Sanctuary. Instead, knock down Stella, Death first. It opens Forest of Doom and adds High Tonic to shop.
  6. From the relationship of item use, Knock Down in the order of Dagon, Region. In Forest of Doom of Dagon Knock Down, using the new out of bounds route, Push Cube and Strength Glove became unnecessary. This completely eliminates the need for Push Cube and Strength Glove.
  7. From the relationship of Final Sword equipment knock down in order of Nest of Evil, Astarte. The later route is the same as before

Attack method

惻Multiple hits glitch is a glitch in which four or more kinds of invisibility are superimposed on enemies and attacks of the fourth and subsequent ones are hit continuously. This memory address varies depending on the enemy. Therefore, it is necessary to investigate accordingly. Below is an example of True Dracura.

Address Size Description
02101005 2 bytes True Dracura invisibility 1
02101006 2 bytes True Dracura invisibility 2
02101007 2 bytes True Dracura invisibility 3

When invisibility 1, 2 and 3 is 1 or more, the fourth and subsequent attacks multiple hits.This time I improved chara change at this multiple hits. In addition, I improved by using multiple hits of Jonathan alone in Whip's Memory.

Mothrayas: Judging.

Mothrayas: Interesting change of route - it's nice to see the new strategy show off some new moves. The rest of the run is just filled with more crazy fast action and ludicrously quick boss battles, as usual. Accepting as an improvement to the published movie.
