I have recently purchased an R4, after formatting my TF card and dragging the zipped files and folder to the root I then draggged some game sto a game folder I created. Power on the DS and go to the .NDS the game menu loads. I select a game and the follwing window populates on the touch screen: FIle info: Not support ext.7Z Anyone ever get this before? I have uninstalled and reinstalled everything onthe TF card several times and have still have been unsuccessful. Any light someone could shed would be appreciated. Thanks.
