Hi, I have two NDS's 1. DSI v1.4.3E 2. DS XL v1.4E I also have three R4 cards. Two with mario on the front and one with R4 SDHC on it. The two Mario ones, as far as I can tell are identical. Both DS's were working with their R4 Cards (Mario ones) but my daughters managed to loose on SD card and the other no-longer works. I have new SD cards but can not get either to run, no matter what combination of files I download from the manufacters sites or using woods files. All get when I run the R4 cards in the DS's, is a "menu" icon, followed by a red, sad menu icon. Can someone point me in the right direction of the files that should be on the SD cards. I have been working on it for three hours with no luck and I need some help now. Thanks!
