Wow, so did this happend to me. I totally been carefull when writing roms and when removing the hardware. Hadn't been flashing/deleting roms for months so I finally thought I should put another GBA rom on it. It all seemed to work fine, I put the fashcart on the burner and then into the USB-port, Windows found it and the burner LED turned blue. After I flahed a GBA rom I safely removed the hardware and put the flashcart in my gaming unit. GBA logo shows up but then it just turned white. Nothing! I put the hardware in and it shows up in windows but no blue LED on the burner. The portable device shows up in "my computer" but I can't access it. What to do?
