I get it,sigh...here we go yet again.
No, it's not the same as the "general release" (Basic). Of course the 2 2023 Christmas scenes are the same... that's not the point though. The difference is Basic versus Extended. Again, this VN always comes in two variants every update being Basic & Extended. I've explained the differences between the two many times for years, I'm not going to do it anymore since there's a perfectly good search bar for that.
But still i cannot see any difference between 1.3.5 Anniversary Extended + Christmas Patch Basic vs 1.3.5 Anniversary Extended + Christmas Patch Extended. If there is no difference between these patches, why was there any pressure for extended version leak?
