I have been able to find 160x160 pixel emoji PNGs from iOS (actually WhatsApp but they are roughly the same set). These only show up as 1x when I import them into XCode 7 though.
Is there a way using Photoshop / OS X or similar to create high-resolution (retina friendly even, if possible) Emoji for use in an iOS game utilizing SpriteKit to animate the emoji?
Thanks in advance.
