hi, I bought this r4 a little while back. The firmware on it seems to have just died... no idea why. When I go to the website listed on the chip ndsiLL.net I can't download the firmware. first question is, is this a fake r4?? The wifi on it does work. The picture is a little blurry, but it says R4 i V1.6, Revolution for DS. It does acept SDHC cards. I have a 4gb one in there atm Any help with the firmware is appreciated!
