Hi everyone. Im new here and pulling my hair out. I bought my kids a Nintendo DS Lite each for xmas. A month or so ago I bought them R4 cards to go with them. They are R4 SDHC cards, they say wifi on the box and card, and have no version number or the circled I on them. Ive tried so many different firmwares. I have a 2GB Samsung Micro SD card, and some 8GB SanDisk Micro SD HC cards. Ive tried both and none work. I always just get a message saying error in red on the top screen on the ds. Im desperate to get these working before xmas or Im going to have disappointed kids, please help!
