Hi guys
I have a problem with my supercard, when I turn it on the supercard it shows like this.
games are woring fine, but when I play the pokemon red the save is not working.
is this something to do with bettery? if so do i have to change it?
does any body knows how to fix?

Try updating the firmware on the cart,

Either way, the SuperCard Mini SD is super infamous for their poor quality, and issues with games.
