Any know what to do with this? Only "Slow" function (repeated pause) seems to do much good. Tried with several different games. Maybe only works with a few games?
I'm not sure what its true purpose is, but I have a write-up on what it appears to do here: http://www.famicomworld.com/forum/index.php?topic=7231.0 (http://www.famicomworld.com/forum/index.php?topic=7231.0)
Nothing special inside

Looks like turbo for built-in pads and headphone amplifier. No more no less
I should have searched first.
Thanks, UglyJoe.
