Not a problem Lisa. ^^"
If a card with an R4 label on it can read MicroSDHC (>2GB) cards, then it *is* a fake/clone. They aren't necessarily malicious, but many users regard them to be made from poorer quality components, which could potentially damage the DS (although most likely it would just fritz itself and your MicroSD).
I can sort of understand why people are still buying/using R4s, because not too long ago (roughly a year and a half) the R4 was practically the best on the market. This is not the case however, as even if you can get hold of a genuine R4 (which is hard enough, considering they aren't made anymore, and there are so many fakes/clones), its features are slim (no enhanced features, relatively dated GUI, limited/buggy cheat support, no support for SDHC cards etc.), and it is having compatibility issues with newer games (because the firmware developers no longer operate, and as such there will be no more official R4 updates/fixes).
I think I can speak for the majority of Tempers that it would be very much in your interests to research getting a newer card. Check the Reviews section for info about particularly the
Acekard 2, the
CycloDS Evolution, and the
M3 DS Real. I use an EZ-Flash V myself, but I've got an Acekard coming through the post soon (to satisfy my User Interface prettiness desires until the EZTeam release a new loader, as they have hinted at recently). Most flashcarts can be gotten from DealExtreme for
very reasonable prices (except the CycloDS Evolution, which is only available elsewhere, and is relatively expensive).
Anyway, good luck with your GBAtemp lurking and browsing.
