Just bought a GameShark Advance for my little brother. However, it APPEARS to be defective. I insert the GameShark with a game in it, but nothing happens only the Game Boy logo. The GS appears to have two switches on the top, but they are not documented in the manual. Can anyone shed some light on this? Thanks in Advance. (No pun intended)

Cheers :beer:
