I just bought a MicroSD card a couple days ago, and when I opened it I found out that the printing was pretty crappy compared the other ones I have. I have a 2GB Toshiba Japan, 1GB Kingston Japan, 1GB Sandisk, 512MB Transcend card and the ones manufactured in Japan all have no problems running Downhill Jam and Castlevania PoR. But the one I got recently (The one with crappy printing) has a slower transfer rate (Speed tested with SCDS1 "Automatic Speed Detection") than the other Japanese ones, and hangs time to time on PoR. (Didn't test Downhill Jam, but I suppose it would have problems) For the speed, it's detected as 2X by my SCDS1. Kingston's website says it's genuine (by a serial check) but I suppose the serial could be duped. I didn't have the time to order another one to check if the serials are the same. Below is what is printed on the card, KingstonÂ 2GB MicroSD 0726K60972V SD-C02G JAPAN SDC/2GB (Pb) The (Pb) is a something that looks like Pb in a circle, it maybe Mb, Pq, Mq - the print is too small and the print quality makes it hard to read, so it's just a guess. Has anybody else bought a card like this?
