I think I found it, you gotta hit A right after you hit the side special.

There a bug/awesome trick with Marth Aeon's side special that the cpu keeps doing, he will go backwards while still facing forward or will release the attack and slash while going forwards then shoot backwards after. I have no idea how to do it but it's cool to see the cpu doing that.

So, this is why I didn't hear any more news about your old sword psa. This is amazing! Can't wait!

@Jack Can't that already be done with Almas "Alternate File Loader/Clone Engine" on Smash Boards? Unless you meant loading more then one on the same person at the same time.
