Didn't notice this at first but I figure I should comment-
You say "Give credit"... For what? Organizing someone else's rips? Even further, you're asking for credit on something you didn't make at all... Nintendo made it. They're the only ones who should get credit for their work.
I swear, asking for credits on rips is the stupidest thing ever. A lot of people seem to think that it's the correct thing to do though, and I say "those people are stupid".
Now, on the other hand, had you made your own sprites, or created an elaborate edit, it'd be totally cool to ask credit.
