Well, debatable on the C64 instance. Indeed, if you can manage to commercially market your design, then you could get a userbase in the thousands. But compare that to the millions of downloads something like Dolphin gets. And the ARM-based mini systems could work for retro emulators in general, sure. Presuming someone actually writes a true bare-metal OS for them instead of just a lightweight Linux instance. But they're not fast enough for people like me that are obsessive about exacting emulation accuracy. I'm still hoping we'll get to a point where ARM-based computers are taken more seriously and we start getting a real market for products like the Jetson TX1 to compete against budget AMD systems. All of this stuff involves sacrifices. The more you chase latency, accuracy, etc ... the more you alienate your potential market. Even when we're not looking for money, more users is such a potent motivator to validate that our efforts aren't being wasted.
