The VG Resource

I've seen some on google. They're pretty good. I cant put them here, because that would be illegal. But you could try searching "silver sonic battle".
If it's not there, either the user deleted it, or it's just hard to find.

Have you checked The Mystical Forest Zone? They've got one there, and another in Advance style.

Yea, I'm talking about this: http://www.themysticalforestzone.com/spr...v_neox.png
