I have never actually figured out how this works or what it actually does. I tried looking on google but it didn't give me any real answers. The results I found just mentions some button combination like L+R+START+UP or whatever, but it does nothing when I press them (I have an M3 DS Simply with R4's v1.18 kernel, just so you know).
So my question is, what does this do and how does it work?
