      I had a question about how 480i is handled on the OSSC. I’ve read that it can be processed up to 480p, but just like how there is a scanline mode for 240p signals, does the OSSC have a mode where it outputs a simulated 480i? As in, on your HD panel you see alternating fields with scanlines?

      I am very curious because for games that were developed during the 480i “era” (PS2/DC/Gamecube/Xbox) I quite enjoy that look.

        Yes, the OSSC has alternating scanlines for 480i/576i.

        It also uses simple bob deinterlacing, so it upscales the fields independently with a vertical offset so that the fields overlap correctly.

        It does not have any adaptive deinterlacing, so details flicker.

        Note though that the resulting line flicker can defeat the pixel inversion used on LCD display, causing temporary image retention to occur much more easily.

          Interesting! I was able to find some off screen footage of OSSC 480i. This gives me something to consider. I’ve got a consumer CRT and I’d prefer to use that, but getting a working set that doesn’t have something about the picture failing is getting harder and harder.
