Let Nintendo develop an Emulator for Android/iOS

I think, many Pro and Casual Gamer, so as I am, would like to play their favorite Nintendo games not on their GameBoy Advance, which maybe died or even doesn't exist anymore, but on their mobile phones. I tried a few emulators for iOS as well as for Android and some of them where good, some of them where absolute garbage.
So I started the petition, to let Nintendo know, that there are a few people in the world, who would like to play their favorite Pokemon, Yoshi or Mario Game, from the old days on their phone. I talked with my friend, who is also a big supporter of this idea, that we would throw our money to Nintendo, just to have a good app where we can play our older games. Even if it's 5-20$, we would support this idea, but just bring us back the old memories and make an emulator. Nintendo would get money and we would get our favorite games back!
