Game Gear

The Sega Game Gear was Sega's first handheld system. It was esentially a handheld Sega Master System. It was in color, unlike the rival Nintendo Game Boy. Sonic Drift 2, the first Sonic racing game sold in the United States, was a Game Gear exclusive. Like the SMS, the Game Gear received all Sonic Games including the SMS/SGG exclusive Sonic Chaos. It was succeeded by the Sega Nomad. Also unlike the Game Boy, the Game Gear required no attached light source, as it generated its own light.

Accessories

 * AC adapter- the adapter that allowed the user to use a wall outlet instead of batteries
 * Battery pack- a portable attachment that lasted longer than the usual six batteries
 * Tuner- an attachment that was designed to provide radio and television stations
 * Connector- attached more than one Game Gear for multiplayer

Problems
The Game Gear was plagued with problems. Because of its advanced technology compared to the Game Boy, the price was higher. The battery pack was almost essential as the system otherwise used the six batteries in fewer than six hours.

Ports and Emulation
The Game Gear, though unsuccessful, still has a cult following and thus ports and emulations have been made. The Game Gear versions of most of the Sonic the Hedgehog titles can be found on Sonic Mega Collection Plus, some being found only on Sonic Gems Collection. Some games are unlockables for recent Sonic titles such as Sonic Adventure.
