Well, I think this topic should be a place where everyone should post his/her ripped sprites from JJ1 or 2, or even from JJA. So, if someone would like to use them for a game or something, they could find it here. (this is why I posted this into the community game development section)
Okay, here are the stuffs I've been ripped from JJ1 today.

I'm not sure, but maybe the little turtle is incorrect. (I mean maybe has some mixing pixels, or has some not needed ones, not sure. This is because of the background... I'll find a better way to rip)
More will come later, hopefully.
And here's the JJ2 turtle again, to let every spritesheets being in one place. See the difference beetwen this and JJ1's?
