"For those of you wondering, he was taking this game apart to use the back on his JP copy of Mario Kart so he could take it to a friend’s house with unmodded N64's. As to why he didn’t hear the pills loose shaking around, they were stuck to the sides with double-sided tape. You can see that in the image. The tape itself also looks old. He bought the game a year or so ago, but the game itself was made in the late 90s so who knows how long this has been sitting in there."
