I tried my hand at making the Brawl roster after seeing the other two previous rosters made with the same site by JJ (who remade 64) and Picklechu (who remade Melee).

Difficulties:
Snake was a tough one to replace. I ended up using Sheik's darker palette because it also fixed the issue of having no Sheik on the roster.
No Pokemon Trainer, so I just used Charizard.
No Ice Climbers, so Duck Hunt (Duo) was used instead.
Finally, there was no Wolf, so an alternate Fox palette was used.

tl;dr : There was some difficulty in replacing other characters, and I'm open to suggestions for corrections on this if any arise!
