Some of the games that have been released have never been give a hd version or made universal. For example brothers in arms hour of heroes. Is there a way to to get them on an ipad?
Download them from the App Store like you would any other app? They'll work on an iPad, just with black borders.
In case you're still confused, you have to select 'iPhone only' at the top of the page. Then, the iPhone apps will appear. I know, it's a bit overwhelming.
