Thank you Zebidee for your reply.
Your post was a bit technical, I'll try to grasp what I can.
As I mentioned earlier, I live in Japan, so no SCART here (or at least it's uncommon)
Unfortunately I am unable to purchase these kind of electronics from Europe (most places don't ship to Japan)
Right now I have ordered the one from Aliexpress, it will take few weeks to arrive tho (usually it takes 10-20 days for the merch to arrive, but it's holiday season, so it might take longer)
Once I get it, I plan to use this cable from the Laptop VGA port:
into the INPUT of the converter box here:
And then using this cable:
from the box output:
into the D1 Component port of my TV:
If the D1 doesn't work, I will try the YCbCr connectors with this cable:
If all of this fails, I will probably give up.
You mentioned that even without a SCART, CRT Emudriver can output the sync, is that right?
Also, I'm curious about your product (you said you'll announce it around end of the year). I am very interested, as long as its not too expensive and it can be sent to Japan.
