I have an official R4i Gold 3DS RTS which has
www.r4ids.cn on the label. How do I determine which hardware revision I have? I'm on the step in the "guide" after installing B9S to remove ntrboot so I can restore the original flashrom.
FYI: I purchased the R4i flashcart in 10/2016 and it has the letter D (or 0?) printed above the last pin on the back.
