Is it possible to download pokemon games onto your iPod touch?

I was going to buy an iPod touch and i liked pokemon so i was wondering if the itunes shop has any pokemon game applications. Like can you buy pokemon emerald version or pokemon platinum and play it on your i pod touch. If this isn't possible to do is there any way to download Gameboy pokemon games or DS pokemon games on to my iPod touch. Please help me out.|||No, you can't play or buy a Pok茅mon game on the Iphone or Ipod touch app store. But you may find some walkthroughs and guides through the original games for DS and gameboy etc.
