I read the comment about the real card versus the clone. Nevertheless, I have an issue and maybe someone can help. I upgraded my son's DS to v1.24b from www.r4i-sdhc.com and it worked nicely for a bit. All of a sudden it would not load. I read something about updating the kernel which I did, and it worked once again... I am not sure if my som pull the card out (He is only 5 and they do things like that), but all of a sudden it would boot and then give me an error. I reformatted the SD card, and loaded the kernel back on as well as the games, and still no boot. Any suggestions would be greatly appreciated!
