I have a Nintendo DS Lite, an R4, MicroSD Card and the SD Card reader, everything I believe I need to use DS2Key. But I'm very new to all of this, so I'm not really sure of the process I have to go through, whether it's a simply drag and drop the files into the root of my R4 and then run it, or if it's more complicated. Can somebody maybe explain or direct me to a tutorial I could use to get me going, please?
