hi, i was having fun playing my games with my new R4 card for the last few days since getting it. a few hours after playing the DS, i turned it on and the top screen reads "couldn't find _DS_MENU.DAT" it was playing perfectly with games on it and everything... so, what have i done/what's happened?? and more importantly, how do i fix this problem which i hope others have had and have overcome.. ANY help PLEASE ??? ?????
Try reinstalling your firmware. http://www.linfoxdomain.com/nintendo/ds/ Get it from that page and just drag and drop it into the root of your DS card.
