I tried to set up the Super Mario 64 DS circle pad patch and in order to do so you have to enable "external FIRMs and modules" but when I do it my 3DS cannot load any DS application, whether that is twilight menu or DSI Wifi settings, they all just stay on a black screen. That is until I disable "external FIRMs and modules" then its all back to normal. I want to install the camera mod but can't since twilight and ds games won't load with the setting on. Anyway how to get it working? Also this is a New 3DS LL from Japan I changed the region of when I was hacking it to USA. Maybe that's what is causing it?
