Looks like not all Arduino Unos are created the same - will my 3d party Uno work with DIY Gamer Kit?

Fantastic, switched the battery clips and we now have lights! Blinking green light and steady red on arduino and red light on slow blink on the gamer. Troubleshooting says that means no games installed? So we've followed instructions for downloading games, but no change on the lights. We've turned power on and off... no change....
