I just bought a new r4 sdhc for the nintendo ds lite. I bought it with a microsd 4gig memory card. I went to r4ultra.com to download the latest kernel version (1.55) and when it was done, i extracted it and it made a folder sayin English-1.55. Then, I dragged all the files from the kernel onto the USB/micro sd memory. I also made a games folder for the memory thing. So after I finished downloading and dragging to the memory, I put the micro sd memory into the r4 and I trned on my ds life and it just showe a black screen sayin loading and nothin happens r4i 3ds buy r4i sdhc
