[pengzhenghao]

Is your feature request related to a problem? Please describe.

YuukiPS provides fixed resources file that support client and grasscutter 3.4 at:

https://gitlab.com/YuukiPS/GC-Resources/-/tree/3.4/

We should update the README / wiki to reflect this instead of pointing to the official reosource repo which is outdated.
