It would be great for people who uses BMC64 with single joystick through GPI configuration 1. Hence, GPIO16 is used to access the menu, typing simple commands like Load, etc. by the virtual keyboard by navigating with joystick makes the BMC64 more portable. Because there will be no need for any keyboard.
Considering BMC lite on a Pi Zero, also there will be no need for USB adapter since GPIO pins will be enough to access menu, attach joysticks and type simple commands and pass trainers or intros by virtual keyboard.
