Hi i had in the past a dsone mini supercard. I now have changes to r4 gold version but i today just found this one again and i tried to give it a try in my dsi xl as in the past worked perfectly. But when i plug it into my ds nothing comes on. It seems like the card is broken but i read somewhere that it supported systems bellow firmware 1.45. Is it real? Can i mod my dsi xl and just run it there or not?
