Notes:Proto:Genshin Impact

This page contains notes for the game Proto:Genshin Impact.

Tools

To do: There's probably more (and possibly better) tools out there. Mainly wanted to list these to help anyone interested in datamining these versions.

• Modified Unity Asset Studio that can directly open the game's blk files from almost any version, including betas.
• Genshin Audio Extractor
• Isolator by hotaru.ys can be used to create sandboxed registry keys for any version. Rename to included .dll file to version.dll and copy it to the game's root directory. Mainly useful for running older versions of the game since most of them share the same registry key with the current release. (source code)

This proxy script can be used with Fiddler Classic to block miHoYo's servers and redirect traffic to server emulators.
