you have a R4i SDHC, but it can't work on 3DS and wood kernel, right?
Of course, R4i SDHC only for DSi , not for 3DS, you have to use R4i 3DS SDHC(red one);
and of course this card can't work with wood kernel, they r4i Gold 3DS can work with wood kernel.
please check the detail information before you order, or it is a waste of money
