So I was trying to update my r4 to 1.26 from r4sdhc.cn or whatever, and after installing it, I was stuck on the LOADING... screen. Upon further reading of the website, I noticed that I was downloading and update for r4sdhc (I don't know what that is). I'm assuming it's a newer R4 card, and since I got my r4 card about 2 years ago, it's obviously not an SDHC. I've tried redownloading 1.18, but I'm not sure where everything goes. So, how can I make it back to normal? I've still got the disc that came with the R4, but nowhere does it say what goes where. Could someone upload a folder of basically a clean, old, R4 sd folder? Also, how do I format my SD card/ is that necessary? Is it just a matter of deleting all the files on it?
