Hey everyone, I'm having some trouble getting my r4 sdhc dual-core to work with ntr, it just tells me "your flashcart is not supported" no matter what I try. I've tried the cfw method and it gives me that message, I've tried the single system method and it seems to inject it but the card still has functionality and if I try to do the sleep mode part of the method it just goes black after a second. Old 2ds btw. thank you
