Yes, there is a large and active Chinese Koikatsu community. One of its primary hubs is a forum called
Zodgame.
This forum is the official publishing location for the comprehensive package we are discussing, which is known as the
Gilleco Package. Within the community, it's often referred to as the "G-dà Package" and is widely regarded as the most popular, stable, and consistently updated version available.
Regarding how to download it, you have a couple of excellent options, and the good news is that you can avoid the difficulties of using
BaiduNetDisk.
The primary and officially recommended method for getting and maintaining this pack is through a tool called
Resilio Sync. No Baidu Needed, P2P syncing, Always up to date, Selective Sync (to avoid full 150 GB). For users who prefer a more traditional download, the author also provides international-friendly options, so you can find direct download links, such as
Mega, on the release page.
Here is a quick guide on how to get it:
Go to the forums and register an account, then locate the
release thread, then find the download information within the thread, keywords like "Download_KK_From_Resilio.zip" or "mega.nz".
