When I was a kid and I had a Game Gear, I was super excited. The thing was way better than my Game Boy, but it only had one big issue. The battery life was horrible. Finally, someone made an awesome mod that makes the Game Gear more awesome: Introducing the Handy Gear.
It has a custom-made case, Master System converter and a 5-inch PSone screen. Most importantly, it has rechargeable batteries. The con? It’s big and weighs in at more than 2 pounds. Not so portable.
