Action Replay code to cut Jigglypuff's Rest sleep time in Super Smash Bro Melee?
I know this is 5 years old, but just in case you're still maining Jigglypuff and still need practice with this combo, I got something.
The 20XX mod now includes a way to save your current state and reload it instantly. For example, you could save you getting the grab on fox/falco, perform the combo, and then instantly reload the saved state of you having just grabbed the spacie, throw them up, down-b them, reload the saved state, do the combo, reload, combo, reload, etc.
A YT video detailing how this works can be found here.
From another Jiggs main,
Good luck! Go beat those spacies!
