I own this Nintendo DSi: http://www.jointheadventures.com/files/pos...llic_blue_2.jpg And this R4i: http://www.phantomcastle.it/phantom/temp/R....0/DSCF4146.JPG It would be "R4ISDHC HappyBox Red V2.0" Producer website: http://www.r4isdhc.com Links for kernel and firmware of this card: http://www.r4isdhc.com/download_v2-0i/ (As support console I own a ds phat gray http://img.clasf.it/2012/11/16/Nintendo-ds...21116115452.jpg and an original R4 which is not compatible with dsi http://www.best-b2b.com/userimg/927/935-2/...ds-card-597.jpg). Unfortunately, this morning I got the bright idea to update the system of my dsi blue to the version 1.4.5E and unfortunately as we read in the link http://www.r4isdhc.com/download_v2-0i/ the latest firmware released is "3DS v4.3.0-10 and DSI v1.4.4 Upgrade Firmware" so do not go for the 1.4.5. I want to know if there is some way to make work well the abovementioned card in the nintendo dsi, or if there is no hope, I would like to know how much it can cost a new r4i compatible with the 1.4.5E. P.S.: I apologize for my bad English, I'm Italian. Many thanks to those who help me.
