nullDC is a freeware Sega Dreamcast and NAOMI, the arcade version of the hardware developed by Sega. It is developed for the Windows platform and is already able to run some games.
That's where I put it. But like I said other people's posts from a day or two ago have no responses. I'm not sure if the chat is part of the Nintendo forum that I'm on or a part of the website as a whole.
I did all of that stuff and it seemed successful but still nothing. The only thing different from the guide I used was that my device wasn't showing up as APX but rather Nintendo Switch.
