I have a clone version of R4i sdhc dual core. I was wondering if anybody ever tried updating these clone flashcarts to work with the latest FW 8.1.0-19... I was able to update this flashcart to work with Ver. 7 (not sure which one) and it worked flawlessly. I only recently discovered that my flashcart was a clone and was hesitant to update since then. Are there advantages of upgrading my 3ds fw to ver 8 anyway??? Thanks guys!
