PAL – All changes in 1.2 are present, but there are many more changes.
Bowser, Kirby, and Yoshi are each heavier.
Marth, Fox, and Mario are each lighter. This puts Marth below the weight threshold of standing up during Fox's shine.
Falco's down aerial only spikes for the first half of the animation. The rest sends the opponent slightly up.
Sheik's up aerial isn't as strong, and has one less frame of hitbox lag.
Marth's down aerial is a Meteor smash and sends the opponent at a 90 degree angle
Fox's down and forward smashes are less powerful.
Fox's up smash weakened, damage dropped from 18% in NTSC to 17% in PAL, knockback dramatically weakened, for example, in PAL-version Peach would die to Fox's Usmash at as high of a % as 83%, whereas in the NTSC version Peach only needs to be at 71% to be Star KO'd at Final Destination uncharged. A fully charged fully stale upsmash could kill Peach at 55% on Final Destination.
Yoshi's forward smash is more powerful.
Peach's dash attack is less powerful.
Luigi's neutral aerial is less powerful.
Ganondorf's down aerial inflicts less damage, from 22% in NTSC to 21% in PAL.
