Hi there, I have a DSi XL which I have a DSTWO card inserted which works fine. I was looking to see if I could use with my 3DS, it currently doesn't work, I get the white text on a black screen when I try and load it. Is there an update for the DSTWO card that would enable me to use it please? I'm not sure what firmware is on the card, but it's a long while since it's been updated. The firmware of my 3DS is 9.7.0-25E. Thanks in advance.
Check out the SuperCard's official page and see if it mention the latest firmware/kernel it got, is compatible with the latest 3DS firmware or not. If it does say so, then update your cart to the latest version provided using your DSi. Clearly your SuperCard kernel isn't up to date if it isn't working on your 3DS.
