The Arcade Turbo Joystick is compatible with MSX,Amiga systems. However it is only suitable for games which require one trigger button as both buttons work as trigger A, for respectively left and right handed users. It is also compatible with older ATARI and Commodore systems that need just a single trigger button.
It is possible to modify the joystick for two independent trigger buttons.
