AV Cable for Sega Genesis 2 and Genesis 3, 6FT / 1.8M Composite RCA Audio Video Cable, 9-Pin Console Connector to Yellow White Red RCA Plugs, Connects Genesis 2 3 to TV

Does anybody know if a 9-pin composite cable like this one here will work with the SEGA Genesis, or does it have to be a specific composite cable. It has to have the correct pinout. Genesis composite cables are readily available. Here's one for a Genesis model 2, which is I assume is the one you have if it has a 9-pin mini-DIN connector. Also, I was talking to a guy one time about using some kind of HDMI converter wire so I can connect the Genesis via HDMI, but he said that would mess up the picture. Is that true? It's true if you get a cheap one. There are specialized upscalers designed for 240p video games, such as the RetroTINK lineup, GBS-C, OSSC, Morph, etc., and those work well. Avoid brands like Hyperkin and LevelHike; those are garbage.
