Hi all, I'm new in here. I would you like to ask you guys to help me out. I have 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 have a msg: The hardware is not compatible. what am I missing? Please help.
