someone have archives of older versions? I think MiHoYoSDK, Version=2.15.0.0, in the resources.assets may be helpful

In my environment, it seems that the webCaches folder specified on line 49 of this script has changed from 2.15.0.0 to 2.16.0.0 with the 4.1.0 update.

4.0.x
$cachefile = "$gamedir/webCaches/2.15.0.0/Cache/Cache_Data/data_2"

4.1.0
$cachefile = "$gamedir/webCaches/2.16.0.0/Cache/Cache_Data/data_2"

Yes, link should be replaced with https://gist.github.com/MadeBaruna/1d75c1d37d19eca71591ec8a31178235/raw/getlink.ps1 -> this will always point to latest version of file

This method by @jogerj should be used to get updated link! Link in the paimon.moe needs to be updated

at "README.md", the code line should be

Global:

iex "&{$(irm https://gist.githubusercontent.com/MadeBaruna/1d75c1d37d19eca71591ec8a31178235/raw/702e34117b07294e6959928963b76cfdafdd94f3/getlink.ps1)} global"

China:

iex "&{$(irm https://gist.githubusercontent.com/MadeBaruna/1d75c1d37d19eca71591ec8a31178235/raw/702e34117b07294e6959928963b76cfdafdd94f3/getlink.ps1)} china"

you have missed the quote " at line ends.

this two commands not work now, I refered to the available version by @jogerj, with command iex (irm 'https://gist.githubusercontent.com/jogerj/0339e61a92e0de2e360c5212a94854e8/raw/get_wish_url_from_cache.ps1')

cn server api host changed to $apiHost = "public-operation-hk4e.mihoyo.com"
