Just got my M3 today and well it doesnt work. When I turn it on without a SD card it tells me theres not one inserted and to restart and insert one or press start to contiue anyway. When I press start it just stays at a black screen. When I do it with a SD card in nothing happens. Anyone have any ideas as why this doesnt work?
http://m3wiki.emuparadise.org/index.php/Media_Card#SD__Cards That is a list of CF and SD cards known to work/not work on the M3, see if yours is listed as not working, that waysyou can be sure if it is your SD card, or the M3.
