About Pokemon Shuffle Sprites

Hello,

I was wondering, since i saw loads of Pokemon Shuffle sprites around sites in different sizes and resolutions..

Why The Spriters Resource don't have extract any sprite from that game? Is it impossible to extract them from 3DS, iOS and Android versions?

Btw, i had read all sections and since this is a question and NOT a request, i hope this is the right section to ask about this.

Thanks.
