Device / iso confusion

[Goddard81]

By wont run, I mean the image thumbnail shows up either blank or white with a question mark, then when I click on it to start the game, it simply doesn't start up. Hardware I dont know much about, I'm not that savvy to it, thars why I need the help lol. How do I find out about the drivers? I haven't changed any settings in the emulator, my assumption being that the default is set as such for the reasons of being the best to use. Same app on each device with same settings, same iso file.
