What I'm trying to figure out is ?? If theirs an internal battery in the Turbobooster that eventually dies where you can't keep a charge on it for all your old game saves/high scores ?? I know as long as you keep voltage running through the Turbobooster it keeps your game scores saved. I would really like to figure this one out because surprisingly at my house and among us Tg16 players where I live my girl has the highest score saved and it would totally suck if we lost that saved high score at some point ...
