Seriously, how absolutely out of touch you have to be from the retro gaming audience to create this kind of thing....
They are making something that is similar to a GameBoy Color, but built on an FPGA, and which lets you play games from a few different consoles.
I grew up with GBC, N64, PS1 and PS2. My first console was the GBC. I played N64 and PS1 at friends houses, and got a PS2 of my own when that came out.
Now and then I use emulation and revisit some old favorites. And I’ve also bought a couple of old consoles second hand to play on those in the past.
A while ago, at the beginning of the pandemic, I bought a Nintendo New 3DS XL second hand with the intention of also trying emulation on it. Ended up only playing actual DS and 3DS games, and not doing emulation. Then sold it.
Not sure I'd want this thing, and can’t afford it at the moment anyways.
But the website did a good job of catching my interest. And if I was in the market for a handheld gaming system, this page would be enough for me to begin looking into it further.
And my point is, there may be more people out there than you realize who are interested in a little bit of retro gaming now and then who will respond similarly positively to that page as what I did.
Sure the MiSTer exists but not everyone wants a project not matter how simple it is.
You are assisting his point by indicating you are not part of the retro gaming audience and you like the page. Personally I will reserve judgment until there are hardware reviews but everything about that page is a "marketing department is in charge of our company" red flag.
