Hi everybody. I bought that card on chips*ain 2 days ago. First, I ve tried on a DsLite, it wont work. Then, on my 3DS and it works. I made the firmware update (all with you guide "how to prepare dstwo,..."). After that, I gave it to my brother and it wont work on his 3DS XL. I formatted the SDcard once again and put the EOS inside. It worked but if I come back to the menu or I shut the console, I got the erreur message "...please shut the console down" at the DsTwo launch. What's wrong ? Thank you.
