Instructions
Insert the CD-ROM into your PC and MicroSD card into the USB adapter that came with the R4 DS Revolution. Once you have inserted the MicroSD card, connect it to your PC.
Drag the firmware file named "_DS_MENU.DAT" from the CD-ROM to the root directory of the MicroSD card. Next load the media kernel and graphic user interface onto your MicroSD card. Once you are finished, create a directory for your games and put all of your backed up ROMs onto the MicroSD card.
Place the MicroSD card into the R4 cart when you have finished loading the files and insert it into your Nintendo DS. Turn it on and the R4 DS Revolution will boot up.
Choose the game you want to play and press a button. Your game loads and you can play the backed-up ROM on the Nintendo DS.
