So I bought an R4 SDHC. I have used it a few times and it seems to work perfectly fine, but in the course of researching functionality of the card, I have run across many different reports of fake cards. The most worrisome thing I have read so far is that there is no such thing as an R4 SDHC, that it is a fake. Yet the site (www.r4i-shdc.com), aside from being written in horrid engrish, seems legit. As I said, the card seems to work fine, I have tried a few games in it. I upgraded the copy of moonshell that was preloaded and it still works. So I am really lost here. Should I be worried?
