Stick with original expansion pak!
Recently purchased the original N64 expansion pak on here, and it allows games like DK64 to work amazingly on my original N64, as well as all my other games! I had previously purchased a third party expansion pak, but it caused my games to freeze. Thus, I would recommend purchase of the original pak for only a few extra dollars!
