Help getting sprites for Pulirula

[Resistiv]

From there, you can scale down the MAME window to the lowest possible size (to ensure a 1:1 pixel ratio), and then screenshot the MAME window using something like Snipping Tool or just press [Windows Key] + [Print Screen]. Then, you can go into an image editing program like Photoshop, Paint.NET, Microsoft Paint, etc. to rearrange the sprites into a usable form. I'd recommend this video to see how to do the rearranging. You'll have to remove those little black dividing lines though...
