Ah, thanks for posting, but I think I should have been more clear.. sorry.

Look, I'm looking for sprites with a small scale, like Genesis Sonic or SNES Mario or Metroid's, around 40 pixels high, and resembling the old Crash Bandicoot, before they did this big change on the franchise.

Look, I found a perfect sprite sheet like what I'm looking for, made by Bandicoota, he had it on devianArt, here's his sprite sheet:

The problem is, he uploaded it as JPG (I don't know why), ruining the sprites completely; he has been inactive for 40 weeks there, I think he has an account in these forums too, but I just can't contact him, like if the guy died or something. I was wondering if there's this sprite sheet somewhere else, or similar custom sprites.

Edit: or perhaps someone here knows how to clean JPG files? is there a way besides recoloring all the sprites pixel by pixel? That's something I wouldn't like to do because of such a mistake, those sprites were really good, what a pity loss :l
