Why is the MiSTer listed as "used to perfectly emulate and/or upscale analog signals?"

MiSTer doesn't just concern itself with analog signals, it simulates the entire system and outputs the original analog signal or can upscale it for digital output on its own. This description could make somebody think it's just a scaler.

Both. MiSTer can output the original signal through the VGA output or through the HDMI digital output (e.g. and using a HDMI to VGA converter), and also it is posible to configure the HDMI output as a scaler (with different modes, from the lowest latency modes using one line as buffer, to the more complex changing the frequency and/or adding low-latency CRT/LCD/etc filters). Effects can be added to the analog output, e.g. scan doubler. Please consider checking the documentation, it is an amazing project.

I am familiar with the project. I’ve owned one for several years, am highly active on the discord and chat with core developers on the regular.

The way it’s phrased in the article linked to makes it sound like it’s “just” a scaler like a Retrotink OSSC. It definitely does fantastic work scaling its own output but it won’t accept an outside analog signal which firmly moves it out of the family of “scaler” to me.
