"My tether for my controller is worn."に関する回答Yes you just need to contact Leap Frogs customer support and they can send you a new one. For safety reasons stop using the controller until you have replaced the broken tether.
"Can I use a computer monitor?"に関する回答You can use a computer monitor as long as there is an HDMI port and built-in speakers.
"What is the battery life?"に関する回答You should expect 24 hours of play time out of two AA alkaline batteries. This can vary depending on which mode you have the controller in.
