Скачать или смотреть SSBM Practical TAS: Marth's Invincible Ledgedash Options [HD]

Four invincible ledgedash options for Marth: spotdodge, jab, roll, and up-b.

How to perform a perfect ledgedash as Marth:

Frame 1: grab ledge
9: drop from ledge (down or away on control stick or c-stick)
10: jump
24: airdodge down-forward (if done properly, you will not spend any frames airborne in the airdodge animation)
34: first actionable frame (perform desired action here)
37: last invincibility frame
38: first vulnerable frame

Notes:

Spotdodge is invincible on frame 2, so you have three frames of leeway. The spotdodges shown here might not be frame-perfect.
Jab's hitbox comes out on frame 4, so the last frame of invincibility is also the first frame you have a hitbox out.
Roll is invincible on frame 4, but you must spend 1 frame in shield before you can roll. If done perfectly, the shield will come up on frame 34, the roll will start on frame 35, and roll invincibility will start on frame 38 (meaning there are no vulnerable frames).
Up-B hits on frame 5, but is also invincible on frame 5. Thus, a perfect ledgedash up-b is also uninterruptible.

About this video:

This video is tool-assisted: it was created by advancing the game one frame at a time and performing every input exactly as desired, then playing back the same input stream at 60 fps. As such, it might contain stylistic flourishes. However, the main purpose of this video is to display a technique that can, with practice, be performed frame-perfectly in real time, and to provide a visual indication of what that technique looks like when done perfectly.
