checked-yes =>Screen Size: When playing original Game Boy and Game Boy Color games, press [L] to stretch the screen to fit the wider GBA screen. Tap [R] to return the screen to the standard size. You can also adjust the colors in original Game Boy games using the same method as the Game Boy Color system. =>Ignore Cartridge: With a GBA cartridge inserted, hold [START]+[SELECT] and turn the system on. The Game Boy logo will appear and a special tone will sound, but it will stop as though there were no cartridge inserted. While the GBA is like this, you can use the GameCube/GBA link cable to send games and programs to the GBA as if it was turned on without a cartridge inserted. If you change your mind, press A on the Game Boy screen to make the Nintendo logo appear and play the cartridge.
