This comes from Adam Koralik's latest video, shedding some light on why the Dreamcast mini probably isn't happening. Having worked with Sega in the past, he has some insight on the matter, sharing what he heard behind the scenes.
"So what's stopping it? Technology," says Kotalik. "If you want to get [the Dreamcast] into a little mini box like [the
Genesis Mini], you really only have two ways to do it. You either build this perfect Dreamcast emulator from the ground up [...] or you do a low-end version that's running PC ports."
Kotalik then recalls a conversation he had with Sega about this very topic, with the company not approving of either option. "The problem is, honestly, that if we want to re-release it as a console, it's going to be 300 bucks [...] Nobody would be happy with a $300 price tag. People would be expecting $100, so people would be mad. [You would] get a high-quality product that just prices too many people out."
