Helpful tips
Change screen size: Press and  simultaneously to change the screen into a smaller size that is closer to an actual Game Gear screen.

Multiplayer: In any game, press on the second controller to make a second screen show up. The game will reset and sync both screens with each other, allowing multiplayer. Some games will NOT have multiplayer, and will just allow 2 players to play the same game on different screens. When playing with two screens on a Non-Multiplayer game, the sound from both games will play at once. This can be done with ANY game.

Play the Japanese version: Go to the Options Menu and switch the text to Japanese. Several of Game Gear games will now be their Japanese version counterparts.
