This was a collaboration between myself and modder seth bones Seth initially was working on it, and then allowed me to finish it up. This includes all 6 alts, metal model and UI. Feel Free to make recolors, and be sure to check out Yoshi in the next update to Super Smash Bros. All Stars!
The mod works great except for one odd error I'm encountering. I've tried replicating it with other Yoshi skins, but it seems to only be happening with this one.
Whenever Yoshi shields, he leaves a purple spark on the stage floor. Throughout the course of a match, it leaves sparks all over the stage. This includes rolling as he turns into an egg (maybe it's something to do with the egg animation?). The good news is it doesn't crash the game, but it does get distracting after a while.
It's possible it's on my end, but I thought I'd let you know in case you've seen it pop up anywhere.
