Sync strippers usually go on the SCART end, the purpose isn’t really to improve the picture as such, more for compatibility with hardware like Extron Crosspoint or XRGB3.
Seems so… Still, if putting it on the console end could have the effect of also improving the signal, even if just theoretically, it’s hard to understand that nobody comes up with this solution. I now want to think that all these cables at least carry sync-on-luma before it’s splitted, in which case I guess it’s really as good as anything.
Yes, pin 10 on the AV out is composite sync.
Ah, thanks. A safe 75 Ohm, 3 V, perhaps? Are Playstations’ RGB fine in this regard too? After a bit of research, seems indeed that the Saturn NTSC outputs TTL, much like the MD/GEN. I really need to ask The Foo about his.
