Just thought i would let anyone who has had problems with the R4 ds cards ie loading games music or photos, like me. I have had great success since I downloaded the correct software to go with the card. To explain i have two R4 cards from 2 different suppliers and each supplier puts their web address on the card, so I downloaded the software from the corresponding web site, and voila ! they now both have games photos and music files that work
Good advice MAZDS123. I've done exactly what you recommended and the R4 loads when turning the DS on, but, I still have the following problem: The "Loading..." screen gets stuck when I try to open a game (any game). My R4 is a neo revolution for DS and the SD card I'm using is a 4GB Sandisk. If you or any other fellow could help would be greatly appreciated.
