Typo or not, he could be partially correct in saying that (BS Zelda).

"Line scan" sounds like it's supposed to be scanlines. Scanline features in emulators are a poor attempt to make the game look more like it's being played on a real TV rather than a computer monitor. It doesn't really ever achieve that feel.

Yes you're talking about the scanlines filter/blitter. However, it doesn't look like a TV, but more like an arcade monitor. TV's scanlines as I recall, are slightly different. However it has a nice effect (for some people) on the image quality. It makes it look nicer to me, less pixelated and dull. There are many types of filters/blitters for some emulators.

Anyways, it's all about what you prefer.
