Hello, I have noticed that a few games will not work on my R4, i was told that a firmware update would fix them. I have downloaded the firmware files and copied them over as the guide on the R4 site says but when i turn on the DS it boots and then has two black screens and the top one says Loading... and it dosnt do anything? what have i done wrong? The R4 says R4 SDHC if that helps. Thanks
