The Top Boy is a giant of a Game Boy accessory that swallows the console whole. It is very similar to the Konami Hyperboy but appears to be unlicensed, with no maker named on the device.

Powerful stereo speakers, a magnifier, front lights and an arcade stick turn the Game Boy into a small arcade machine, powered by two D batteries. The collection also holds the Konami Hyperboy and the Saitek BoosterBoy, the other accessories of this arcade type.

The PowerBase is a docking station for the Game Boy combined with a rechargeable battery system. The pack fits directly into the battery compartment in place of AA cells, and the set includes a mains adapter and a charging base that recharges the pack at home or powers the console directly. An LED shows the charge status, and the base has room for up to four cartridges. The packaging quotes about ten hours of play per charge.

Made under the Gamester LMP brand, the PowerBase was a commercial failure and was produced in limited numbers, which makes it a scarce item today. The simpler LMP Power Pack is also in the collection.

This is a 6V AC adapter for the Game Boy, made by Technoplus, that lets the console run from a wall socket instead of constantly changing batteries.

It is one of several mains and rechargeable power solutions in the collection, alongside Nintendo's own battery packs.

The Joyplus Handy Power I is a quick-charge battery for the Game Boy, working much like a power bank. A 90-minute charge gives about 14 hours of play on the Game Boy, and a thermal sensor guards against overloading.

It was made for both the Game Boy and the Game Gear, on which it lasted around two hours. The later Handy Power II is also in the collection.

Because external power banks were often seen as bulky, some makers built rechargeable packs that fit straight into the Game Boy's battery compartment. The Joyplus Handy Power II is one of these, replacing the four AA cells and giving up to about eight hours of play.

The earlier Handy Power I, a quick-charge external pack, is also catalogued in the collection.

The Attache by Nuby is a carrying case for the Game Boy with generous room for games, headphones and Nuby's own accessories, from the Game Light and Magnifier to the AC and car adapters, Power Pak and Amplifier.

The Game Boy was built tough, but its display was always the weak point, and a bad knock could finish it. This tempered-glass screen protector sticks onto the display and guards it against scratches and cracks.

It is one of several screen-care items in the collection, alongside replacement lenses and decorative screen covers.

The Cool Screen by Naki let players give their Game Boy an individual look. It is a replacement screen protector that came in various designs to suit different tastes.
