That's 0 for 2 on AtGames products. The Flashback 8 Gold I received won't respond to the controllers, or to wired controllers I've connected. This... vexes me somewhat.
It's a sign! lol Not an authentic experience anyway. If the controllers worked and you got playing the games, be other issues that detract from the experience anyway. Every flashback I ever bought wound up back in its box sooner than later.
