+ This peripheral device, which adds two extra buttons to an
+ ordinary single-button joystick, was packaged with the Atari 2600
+ version of Omega Race. CBS Electronics also advertised it as a
+ pack-in for their unreleased 2600 title Wings (it does not work
+ with the known prototype). The homebrew Thrust games optionally
+ support the Booster-Grip as well.
