I have a "New" 3Ds XL, but I'm not comfortable messing with the software or hardware myself. And I think the modded one I found was cheaper than Kity or Loopy. I just need to know if the software they've suggested works because when I tried to download it on my computer it either said "incorrect parameter" or my security told me it (the kit-kat file) was infected with a virus.You are essentially paying for what you can get for free , in the part of streaming since it is using software.
If you want real capture card lookup Katsukity and Loopy.
