Hey, it is a real pain to buy a cable plus shipping which is the price of another cable so i wanted to make my own cable
i have a bunch of 8pin male connectors and high quality scart cables that can be cannibalized. I want to use the cable only for my MINIGUN with 8pin din (i ordered the PCBs and parts just few days before 9pin version was posted, my luck)
But since i'm not that much familar with all the possibilities i have some questions:

But since i'm not that much familar with all the possibilities i have some questions:
- I pretty much follow the pinout i have here:
I assume this will be okay? - I'm not sure what is the difference between TTL sync and Csync even though i tried to read about i just dont get it how it works technically, people just say what are some differences between them but not in detail how they both work?
- I plan to use the cable mainly on my old RGB CRT TV, possibly a SCART switch. In the future i will probably buy something like OSSC or some retrotink box. I heard stories that not all cables work with some of these devices, and sometimes you can even fry them? how to avoid that how to work with that? It has something to do with this sync issue?
- is the COMPOSITE VIDEO (pin20 on scart) considered the SYNC pin on 8PIN connector? what about that TTL CSYNC shenanigans?
- do i really have to ground all those pins? 5,9,13,17,18,21(case) togethere? i read somewhere that this is not necessary as long as the 18 and case-pin are grounded together?
- can i ground audio-ground to the regular ground ? i dont intended to split the audio signal outside the scart so maybe i dont need that ground at all?
