for developers to port Master System games to the Game Gear. Because of Nintendo's control over the console video game market, few third-party developers were available to create games for Sega's system. This was a contributing factor to the large number of Master System ports for the Game Gear. Likewise, because of this, the Game Gear library contained many games that were not available on other handhelds, pulling sales away from the Atari Lynx and NEC TurboExpress and helping to establish the Game Gear's position in the market.

This version includes a newly developed Game Gear title G.G. Aleste 3 as well as four other Aleste titles.
