I don't know anything about Photon, other than it is one of the several Flash enabled browsers. However the Puffin Web Browser supplies virtual trackpad and game controller keyboards; and it has a time limited free version so you can see if it works with your sites.
All iPad Flash enabled browser work by using remote serves that can run Flash. That means none of them will work with content that can not be accessed from the internet. Your homemade games would need to be on a website, not stored locally.
