For my buck it's gotta be ClassicBoy for performance & stability. Faster N64 than retroarch and gamepads are easy to set up. Uses PCSX-reARMed and Mupen64Plus plugins. Although it doesn't have a cool, graphical game picker, be sure to check it out.
Update: This Version of RetroArch Works great with Gamesome.
Only problem i have with classic boy is when playing a n64 game, if i accidentally press a button on the controller that isnt preprogrammed to any action but is simply blank, the screen will always go back to the main menu. Its as if it acts as the back controller. Tried adjusting the settings as too not have the back button be programmed to any button but it still didnt work
Looks nice, will def give it a try! Are games launched in "full" screen? Looking at the screenshots from the Play Store it seems like there's a black frame on top and below the image. Anyway to make it fit the screen even in 4:3 ?
If you are upset that Retroarch(July 4) has no Back Button Mapping for the ShieldTV, try THIS ... you have to disable the overlay each time though.
Anyone know a good way of getting roms onto the shield? Like an app to transfer or something
Look for gamesome in the app store. I don't have an android TV device yet but I saw it on this video and it made an impression http://youtu.be/IJEwiHBwKoM
