The Game Gear may bring more to the table than the Game Boy in some aspects, but it left quite a bit in the toybox. You're going to need plenty of power for this amazing color gameplay, and all of that power is a heavy burden to carry. Also the screen magnifier. And the Master Gear Converter. Here are the Game Gear accessories I've picked up.

The Game Gear Battery Pack attaches to your belt or waistband with tension-based clip, and uses a lengthy cord to connect to the Game Gear itself. It can be recharged, even during play, with a Sega MK 2103 AC adapter. This adapter comes with the Game Gear and the Sega Genesis model 2, in case you don't want to buy a spare.

The Sega PowerBack attaches to the rear of the Game Gear by means of a screw, and plugs into its DC power jack. This way, the battery pack practically never has to be removed, if you don't mind the already large Game Gear gaining even more mass and volume. Hope your cargo shorts have massive pockets. The PowerBack is recharged with the Sega MK 2103 AC adapter, the same variety used for the Sega Genesis 2. As always, be careful with battery packs. Don't store them in hot places, or anywhere that may experience wide temperature changes.

Essential for co-op or head-to-head play with another Game Gear, since the system isn't made for connecting extra controllers. Then comes the challenge of finding somebody else with a Game Gear, who also has the same multi-player games you have.

The Game Gear version of the Game Genie features a window which allows you to see the back of your game carts. This sounds silly at first, but this allows you to attach adhesive labels to the backs of your games, with codes printed or written on them. Should you not wish to stick stuff to your games, the included code booklet comes with many codes already, and resides in a compartment like the Game Boy version of the Game Genie. Very handy! As cheaters never prosper (or run into serious trouble with dangerous people), you should always do your best to achieve proficiency in all of your games before using the Game Genie with them. Blazing through everything with invulnerability and infinite weapons will burn the games out quickly, and they're not cheap.
