You mentioned lag from too many vertexes if you did final smash eyes in the submission... Maybe you already used it but the Egg Dragoon fight has a lower poly Modern Eggman model that might fit in better with the Wii's limits instead of whichever might be commonly out there, which might help that?
umm classic eggman was the main problem with the FS eyes...since geneations + umvc3 = 100000 verts soooo....yeaand thats without prooptimizing..with it classic eggman had..44000...so i had to delete somethings....which led to...28000? so yea.......NO FS EYES! lol
I love the new model over dk. But i have shadow over him, so...yeah...
you do realize that psa is ported over GW right?......so you can just replace him
