I can confirm that it works on PS2, Battlefield, Smashville, Dreamland, Lylat, FD, Norfair, FoD, and Skyworld,



How does that mean it's practical? Not often, as it is VERY situational, and on Norfair, FoD, Dreamland the timing and location are pretty strict on where it will safely have you ledgesnap. Now it's absolutely great for Skyworld, Smashville, PS2, Battlefield, and Lylat, as there are much more locations where you can perform this to get ledgesnap.



At times when you are too deep into the middle of the stage it is possible to side-b wavebounce? (I'm not too particularly sure if this is the correct term, but when performed in the air it will cause you to perform the animation in the direction roy is facing, but your momentum will shift backwards) and make it possible to recover with this method when it isnt possible with only this new tech.



It is possible to overshoot and end up freefalling to your death, so it is not completely free



I used the 2nd method described, even then it's still pretty hard for me to think that I could pull off since I hold it pretty standard and this had me being prepared to do I still struggled.



Anyway good find, it will benefit those who practice and learn the uses.
