Hi, Im just got myself a Supercard DSTWO and I can't get it to boot. I quickly assumed that it was the firmware that was the issue, but now I am not sure. Here is an album with all error-screens i have received: http://imgur.com/a/Ylnq7 The first thing I did when I got the Cart was to load EOS onto the MicroSD-card and then try it in the 3DS. I got black and white screens: http://i.imgur.com/fPsgvX1h.jpg I then tried it in my DS Lite, and got the error "An error has occured": http://i.imgur.com/yIT1p5Ph.jpg I then tried the same with an older version of EOS without any luck. I then tried to switch the MicroSD-card to another one I have but got the same error-messages. I then used Killdisk and SDformatter to wipe the SD-card so that it was as good as new, and then tried again. Still the same "An error has occured" on the DSi and the black and white screens on the 3DS. After trying all versions of EOS, patched and unpatched, I had to give up and accept that it was a firmware issue. So i dug up my DS LITE with version 5 firmware and tried it on there. The DS Lite got the same black and white screens as the 3DS: http://i.imgur.com/CmlgWK8h.jpg Now I don't know what to do. Does anyone have any suggestions? Is my DSTWO faulty? I also wonder why I see the game title "Alex Rider" when I read other people see "Fish Tycoon"? 3DS firmware: 2.2.0-0E DSi firmware: 1.4E DS Lite: Version 5, Magneta Check out the whole album here: http://imgur.com/a/Ylnq7 EDIT: I have found the problem and the solution was simple! After getting the same error on a brand new DSTWO I was stumped. I knew I wasnt doing anything wrong, so the SD-card had to be the problem. Then I realised that I've been using the USB-adapter that came with the DSTWO. Big misstake. I dug up Another adapter for the SD-card and formated the SD again. Now it runs perfect and ive updated the firmware so it even runs on the 3DS. There should really be a sticky that warns people not to use the adpter that comes with the DSTWO. Still a big thanks for your help guys!
