I do not care about the implementation or how to implement hardsync (I already found a better solution), but what freaks me out is that I copied the patch and it's not working like the post did. He only posted a picture of the patch, but I copied it exactly and it's not working, maybe someone out there could help check if I'm crazy and did something wrong, or if there's a bug or something.

find attached the picture that was posted and my patch. thanks
