I have a R4DS flash cart and I have been using it for a while now, about a year or so. I had the YSMENU firmware and it never gave me any problems. I played the DS yesterday, and when I turned it on today, I only get a black loading screen and it stays there. I tried formatting the sd card to fat/fat32, even tried the 1.18 R4 kernel and 1.05, and tried it on another sd card, and it still stays at the loading screen. Even when I insert the flascard with no sd in it, it gives me the Loading screen instead of the no sd card screen. Does anyone know a fix for this? Or is it telling me to buy another flashcard?
