The Virtual Boy controller has an NES-compatible protocol, and has been used in homebrew games.
- Spook-O'-Tron
- Candelabra - Estoscerro
After strobing the controller, the following 16 bits can be read from the data line:
0 - Right D-pad Down 1 - Right D-pad Left 2 - Select 3 - Start 4 - Left D-pad Up 5 - Left D-pad Down 6 - Left D-pad Left 7 - Left D-pad Right
8 - Right D-pad Right 9 - Right D-pad Up 10 - L (rear left trigger) 11 - R (rear right trigger) 12 - B 13 - A 14 - Always 1 15 - Battery voltage; 1 = low voltage
This is very analogous to the SNES controller, which reports its 4 face buttons where the VB reports its right d-pad. However, the last 4 bits (B, A, 1, battery) have no correspondence in the SNES controller report. Use this 1 to distinguish the Virtual Boy controller from that controller or a mouse.
