Falco changes from that file:



Down smash has more kbg: 0x4C -> 0x4E.



Usmash is... interesting. It starts one frame earlier (frame 7, from frame 8), and it seems to now have partial invincibility on a few bones (bones 8 and 9 when it starts hitting, bones 5 and 4 when it moves to the next hitboxes which if I had to guess are basically upper body invincibility adjusted for the way Falco contorts himself while usmashing). The first hit has a shifted position ("X" on a few hitboxes, has more bkb (0x3C -> 0x46) and less kbg (0x19/0x1E -> 0x12), all of this presumably to make it link better into the second hit (there's also a strange unknown function added here that is obviously setting a flag, and the late hitbox for the first hit is in a somewhat different X position too). The main hit (the second hit) has similar positional changes to the first hits but strictly improved knockback. kbg 0x62 -> 0x68 and bkb 0x1E -> 0x1F. Then after the hitboxes finish hitting that same unknown function is called to remove whatever flag it originally set.



The unknown function for usmash is unk_853CD75E. After this post, I'll go digging, but if anyone else already knows what it does, that would be great. It seems like it's probably something of mechanical consequence.



Those are the only two Falco changes in his moveset file.
