Hyea so I'm new and need some help with adding characters...

Independently I can add

and

Cloud http://forums.kc-mm.com/Gallery/BrawlView.php?Number=5371&Moderated=All

but since they both go over Ike, I can't figure out a way to add them both, is it possible to have both characters or must I choose between them?

Also...How do I add more character slots? In the video of Shadow, final ver.

I see that sonic and shadow are both playable, how is this possible if shadow is a texture of sonic?

Just wondering if there are more character slots, I also play mugen so I'm a fan of many character slots....
