Use a single joystick to play games without swapping ports
Top quality metal switch with 3 settings: 1 or 2 (joystick functions in that port), or Both (works for most games without changing setting). Makes it safe to use any DB9 controller from COMMODORE, SEGA MASTER SYSTEM, MSX, ATARI, etc as a single button joystick. Analog switches prevent incompatible joysticks (like Sega Genesis or MegaDrive) from causing harm. 3D printed ABS case.
