Hi there I'm new here but can anyone help me out with this dilemma? I've had an R4 for almost 9 months now and it seemed to have stopped working a week ago. It started when I was playing Rune Factory, I closed the lid and heard a strange noise coming from the DS. Kind of like "THUMP THUMP THUMP ad infinitum" I was confused horribly. I open up my ds lid a smidge to check it out. Apparently the top and bottom screens were flickering black and white over and over again like a rave party. I was shocked and turned off the DS. After this all my games started to freeze 5~10 secs in of playing them, doesn't matter what game. I looked the problem up on google and it said to reformat my DS, which I did. It helped for around 2 days but afterwards it started again. I wasn't going to format my saves every two days so does anyone know how to fix this?
