Gameboy Cartridge Keyring

I love going to video game shops and one of the certainties is that you will find shed-loads of old Fifa, Madden and NFL games and also you will find butt-loads of Mary-Kate and Ashley games. Well, I always wondered what the shops would do with these as no-one really plays these games, as there are new iterations or their moment has gone, so all they do is take up room. Well I went to a retro gaming shop called Critical Mass in Exeter and they came up with a novel idea, break open the cartridge and use the circuit board as a keyring! Well, people will probably use it more than some of the old games and it's useful... unlike old Gameboy Advance Barbie games! I think it makes a nice stocking filler for that geek in your life.
