(translated text) "Dear customers who resell Nintendo 3DS " "non purchase able 3DS system" In case if you use equipment which is illegal or unapproved by Nintendo or if you do customization which is unapproved by Nintendo, there is a possibility that Nintendo 3DS become non bootable by system update. - From Nintendo 3DS terms of agreement Because of terms of agreement above, Enterking refuses to buy 3DS system with record of illegal or unapproved equipment. "Request to format before you sell" To protect from leaking your personal and internet connection information, We ask customer to format system. In case purchasing could not be established after you format 3DS system, Enterking is not responsible for lost datas and settings. Please understand before you format.
