Hi I just brought a supercard DS One SDHC. I am using a class 2 sandisc 4Gb sd card I know these are not good micro sd cards and I am going to order a Kingston (japan) but before I order the new sd card I just want to check something. Even the simple games like tetris and brain training crash mid-game in fact only about 1 out of 50 roms work ok the sandisc sd card should be working better than that right? I have formatted it using the panasonic formatter and upgraded firmware with no luck. Do you think I have a faulty supercard or could it be just down to the micro sd card?
