Add the launch SFX from Up-B, change the SFX for the whiffed grab (the one that's used in Melee but that is too quiet to hear when you have music in the background), add an SFX for Side-B (after the start-up, you only use the one that's Fox's voice line, not the actual SFX for the move itself).

These are just small nitpicks. I'm a fan of sound effects when they're done right, so having all of these missing bothers me a little. More Melee hit and swing sound effects would help too, but that's just my personal preference. I could turn that into a different mod if you'd prefer that.
