Hi, i just got a supercard ds two for 3DS XL, version 6.3.0-12U. I upgraded to the lastest Supercard firmware, formatted the sd card with the panasonic tool and i copied games using the dongle included with the supercard. I bought a sandisk sdhc card 4 gb, and I didn't check the class when i did. Currently i can only load a "Lost in blue 2" rom i have on the sdhc card. I switched the card to another sandisk sdhc 16 gb (My cellphone's) and this one card can play some more roms that the other card can't; the just freeze in the supercard loading screen in patch mode, or send a white screen on clean mode. I also tried trimming roms using nds tokyo trim with no results. The only conclusion is that both my sd cards are too slow , maybe they are a class 2? how do i check the class of a sdhc card, is there a tool for that?Is class 6 good enough ? Do you think there is any other reason i'm getting a freeze? Edit: Ok i just checked the card and it's actually a class 4... so what now?
