I Broke My Brother's Favorite Game

Yesterday I did something I know I shouldn't have. I broke my brother's favorite game. He'd been playing it for hours every day, and he was really into it. But I got tired of hearing him play all the time in his room, so when I saw an opportunity, I snuck over to his desk while he was out getting snacks. I found where he kept the controller and just pushed a bunch of buttons until I heard a click. When he came back and tried to play, it wouldn't turn on at all. He looked so upset, but I couldn't say anything because that would mean I did it. Now he's trying to fix it or maybe even replace it, and I feel terrible inside. What should I do? I know saying sorry will make him mad for now, but it'll hurt more if I never tell him.
