Hi all, I am new in this forum. please help with your knowledge. I just buy a R4 DS, after I start install a hardware followed the R4 manual. I try to connect the TF card to DS Slot-1 with the R4, turn on the power. On the screen the R4 Revolution is on (showed), but in the main screen I got this msg: The hardware is not compatible. What am I missing or do something not correct? Please help.
