240p composite downscaling with the OSSC Pro

[osscboy]

Hey!

Since I learned that the OSSC Pro with the Extra AV Out Extension can output VGA and HDMI simultaneously, I had the idea to connect it first per VGA to Scart to my CRT and use the other Scart plug on my tv to connect the HDMI-Out over composite (OSSC Pro >> HDMI cable >> Composite converter >> composite cable >> Scart adapter) to basicly get a true analog „composite shader“ when using Retroarch for PSX, Saturn (and below) emulation.

Since the OSSC Pro can‘t output composite natively (right?), I bought this converter by Tendak.

Problem is, it only outputs 480i. Amazon didnt specify that fact. -_-

So I tried to find converter that also support 240p but my search turned up nothing so far.

Do you guys have a recommendation for another converter or a different solution to this problem?

PS: For anyone wondering, those scaling artefacts and shimmering I was complaining about in my other thread, after two months trial and error I figured out it was my own fault because I tried to get rid of overscan by adjusting the advanced timings on my first day. After resetting everything to factory settings the picture is completely fine.

You might want to wait for a few weeks as there is new prototype Extra AV Out card in making.

OOooooh, and the new version features two outputs side by side, composite on top of the regular VGA output? Or is it composite compatible over VGA?

When populated with optional parts, it additionally supports cvbs and s-video. VGA should not be connected simultaneously, however, to avoid double termination. PAL50, PAL60 and NTSC support has been verified with both interlace and non-interlace modes.
