Password

Choosing this option will take you to this selection screen:

The bottom choice instead takes you to this blank password grid:

I've yet to figure out what this screen is for. I've tried putting in a working password for Rockman 6, but it didn't do anything - I think you have to use it with the base Rockman game for it to mean anything, but I haven't tried it yet. The directional buttons move the cursor around the grid, while the enter button will cycle between placing a black circle, a white circle, and removing the circle from the square the cursor is on - because of every directional button being used, to exit you must hold one down until this screen shows up:

The top option will return you to the password grid, while the bottom will return you to the first selection screen.
