Hiya! my 2013 white dualcore cart decided to go numb... it's this one: http://www.r4isdhc.com/download_white_new2013/ it was working fine and now seems like it's not reading the sd or something... I have tried with both another sd and a dsi - ds phat , all behave the same: dsi -> an error occurred blah blah screen phat -> white screen both consoles show the spongebob game and the card was upgraded with the latest firmware both consoled behave the same with either ds or no sd at all it seems kind of hard to resurrect it but it doesn't hurt to ask! thanks! edit: tried the hot-swap method involving the firmware updater and another working card but no luck, the updater just detects the other card and complains about a very low fw version and there is no retry/re-dedect or whatever... tried swapping the cards during the "loading" message but couldn't make it work either.
