PlayStation 3 and Xbox 360 Sonic Adventure DX DLC
Several of Game Gear games will now be their Japanese version counterparts. Play the Japanese version: Go to the Options Menu and switch the text to Japanese. When playing with two screens on a Non-Multiplayer game, the sound from both games will play at once. Some games will NOT have multiplayer, and will just allow 2 players to play the same game on different screens. The game will reset and sync both screens with each other, allowing multiplayer.
Multiplayer: In any game, press on the second controller to make a second screen show up. Change screen size: Press and simultaneously to change the screen into a smaller size that is closer to an actual Game Gear screen.
