Item Switch

In Super Smash Bros you must unlock the Item Switch Screen by playing 75 vs mode matches. You can then Switch Items you want in the game and you can also change the Appearance of Items to High or Low [Dosen't work in 1-Player].

In Super Smash Bros Melee you don't have to unlock it. You get a lot more Items in Super Smash Bros. Melee, Still the same as above.
