Thanks for the quick response.
The thing that throws me is point 3 / 4 - So once I had set this up there is no need to setup an emunand? How do you go about updating the sysnand without losing access to your entrypoint or is AL9H the entry point? Also because it's a sysnand what happens if I accidently brick it by installing or removing the wrong thing?
Apologies for the noob questions just it's been ages since I used my 3DS - I used to just use the gateway emunand.
Thanks
