I've cleaned the pins several times and it still doesn't work. So I thought I'd open it up to get a better view of the pins and see if anything else is wrong.
Thing is...I can't figure out how to open it! It has no screws. D:

I noticed this thin slot on each side and carefully tried using a small pocket knife to see if it'd catch on some sort of latch, but I'm afraid to force anything and cause damage so I didn't get far on that.

I did notice the game isn't flush on the bottom anymore though, so I did something I just don't know what. :/

So what's the trick here?
