A few (7-9)of my resent new games that I downloaded (even from different web sites) couldnt open them. When trying to boot them up they will free with screen empty and clear, other will go black and said no info found, turn off and re-insert card, other will open into the main menu,but no more further than that. Ihave this same R4 revolution for ds since more than a year ago, I wonder if someone had this same problems and if there's a fix or resent program that I need to download. I will thanks all suggestions.
