My son upgraded his DSi to the v1.4 and his R4 card wouldn't work. They have now brought out the upgrade and to install this you have to put the r4i into a dslite or ds not upgraded to install it. I did this and followed instructions but all I got was the word menu on the top screen and nothing on the bottom screen. Apparantly you should get the upgrade on the bottom screen to install. Has anyone else had this problem and did they get it to work. It's a black box ndsr4i.com and now when I put it in I get the update file on the screen but when I try to load it says invalid cartridge, does this mean my r4i is faulty.
