If your CMS2 game launcher is showing blank server names, you need to enable Chinese PRC in system locale. But this guide will show you how to emulate Chinese locale for MS2 specifically using Locale Emulator instead of through Windows settings.
Download Locale Emulator
Install Locale Emulator and set up the game with these steps:
Right click the game shortcut and click Modify Application Profile
Use these settings
Location: Chinese (Simplified, PRC)
Timezone: (UTC+0:8:00) Beijing
[x]Fake system UI language
Then launch the game using the profile created.
It should show the server names after.
We will be playing on the 女王镇 server.
