I have modded various 3DS/2DS systems now, some of them for other people. When I modded someones 2DS, I remember being told by the guide to use DSP1, then delete the .cia. I haven't used this with any of the other 3DS I've modded, including my own. Should I run this program? I don't really understand what it does, can someone help me? Do I need it, or is it optional? Is it just for using sound on the homebrew launcher or something?
