Yeah, I know Skips had contacted you regarding some of the, shall we say, poorer looking mods. This scene is dominated by modders like Drakon who literally don't give a shit about craftsmanship and will just encase everything in hotglue. And if you show people, who don't know any better, this they will think it's normal and acceptable. Which it is not. This is something, here on this site, that we take pride in showing off with better modding practices. I just had a look over your site again and you have really upped the quality of your mods.
As far as the H+V sync goes, there are both simple circuits and sophisticated devices (like the Extron SS200) that will combine them into proper composite sync. By just connected the two together via a T you are putting a unsafe load on the graphics hardware that could potentially lead to failure. Will it work? Yeah, usually does. Recommended for long time. No.
Composite sync isn't just literally H+V twisted together. They need to be muxed together in a specific way as to not cause issues.
