Setup Guides - Game Boy Color
To set up your Game Boy Color you will need two AA batteries. The system itself does not have any games preloaded, so to use it you will need to insert an original Game Boy or Game Boy Color cartridge (sold separately). Insert the game cartridge fully before powering on the system. The cartridge WILL NOT read if inserted after the system is already powered on.
If the game cartridge isn’t reading, the contacts may be dirty. While blowing into the cartridge can be a temporary fix it can damage the cartridge in the long run. It’s recommended to use a cotton swab wetted with rubbing alcohol to clean the cartridge. You can apply a lot of pressure without damaging the contacts.
The Game Boy Color does not have any sort of lighting built into the screen, so playing it will require proper lighting or a light accessory (sold separately).
