Doh ... I think that I just finally understood Micheal Katz's perspective and reasoning for the Retro VGS.
The actual hardware that's inside the thing is totally
irrelevant to his business plan.
He's selling the experience of owning
big cartridges in
big boxes ... with
pretty manuals ... just like yesteryear.
It'll be a Chinese Android/media-playback SoC ... the reason that he's agonizing over whether to have NTSC or HDMI output is just a case of choosing
which of the alternative chips he'll use.
Any of the recent ones will be able to do a decent 2D game ... which is what he wants ... so no need to pay for an expensive Nvidia Tegra (which would also have licensing restrictions on the graphics drivers).
The console will run a simple uBoot loader from internal flash/rom, which then loads the actual game/linux/whatever from a nice-and-cheap parallel flash chip in the cartridge. It'll be encrypted to discourage piracy.
Instant booting (to a logo screen), and no OS on the console.
If the cartridge contains a simple linux system, then it will run Unity on this kind of hardware, which will make modern indie "retro" developers happy.
Since the main board would be made in China, the choice of the jagwire case and cartridge could be as simple as a way to discourage cheap knock-off production.
If the whole thing is made in China ... then the factory just runs off an extra few thousand boards/cases and sells them online ... which takes away from his profit.
If he's the only one that has the mold for the cases/cartridges ... then it doesn't 100% guarantee to stop that, but it certainly does make it a lot more expensive for someone to do, and so unlikely to happen unless the Retro VGS is a huge success (in which case he's already got a lot of money and can afford to sue).
