Since you're working on model imports, I have a question for you. It'll really help improve the character hacks I've worked on, including a properly scaled Classic Super Sonic (without re-animating,) properly shaped quills for Super Silver, and an easier way to make other models replace the Super Sonic skill. I'll just be glad to have skeleton-repositioning + re-rigging + model/vertex editing + full model importing as options (Just like Super Smash Bros Brawl modding.)
Thankfully I've already stopped coming up with 'those types' of fancharacters long before this game came out. I'm warning everyone, if I work this out and I see someone putting a fancharacter I'll never, ever, forgive you.
