How do you edit character’s attacks in super smash brothers brawl?

Ideally i am wondering if there is a solution where by I can take all the motion paths together and move them in unison so they are all relative to one another.
I have downloaded a flash player screensaver. There are some unwanted popups and sounds in the flash player. Is there any free software that can be used to edit such flash screensavers?

If you go to youtube i see that some people have editted the game to input current rosters and what not. I was wondering how do they do that. Is there any “How to” out there that i could look at to input my own rosters and what not.
I have created a drop down menu system which is triggered on click. The problem I have is that the motion paths I have created downwards are too long and if I edit each one individually there is a chance they wont align correctly once the animation is finished.
Any help would be greatly appreciated.
