<human>: Can you succinctly summarize the text in 1-3 sentences?

I have an iPhone 5 (and I don't care about your opinions on it) and I'm looking to get some game boy games for it. All of the games in the App Store are boring as shit and you can either beat them in 10 minutes or they are trying to make you buy special coins from them. I'm really looking to get some long-lasting games I can play, and I know game boy games are great for that. I used to have an emulator on my android, before it broke, and I could get any game boy game for free and play whatever I wanted(about half didn't work, but it was free). I gad pokemon going and a few others. I want a similar thing going on on my iPhone.
<bot>: does anybody either know any really good games on the App Store or know how to get a game boy emulator on a (not jail broken) iPhone?
