It had recently come to light that the latest iPhone SDKs have an undocumented class that allows for apps to output its video to Video Out rather than to the screen.
This is the result:
Outputting to video-out resulted in a performance hit, so the TV version of the game can only reach approximately 20 frames per second. The game normally runs at 26 fps on the native screen. Freeverse notes that this was all thrown together in a few hours, so there is room for improvement.
It's not clear if and when Apple might allow developers to officially release Apps using this new functionality.
