PaimonMultiplier

Server backend reimplementation for Genshin Impact.

Originally forked from NahidaImpact (xeon). This fork is maintained by NeuronPulse.

Building

dotnet build PaimonMultiplier.sln
# Requires .NET 8 SDK

Running

Launch PaimonMultiplier.SDK (port :8888) and PaimonMultiplier.Gameserver (port :22101) together.

Connecting

Use PaimonMultiplier.Proxy — launch it and configure your system proxy. SDK requests to *.yuanshen.com, *.hoyoverse.com, and *.mihoyo.com will be redirected to http://127.0.0.1:8888/.

Architecture

Project	Role
PaimonMultiplier.Proxy	MITM proxy on :8080 — redirects game traffic to SDK
PaimonMultiplier.SDK	HTTP server on :8888 — region list, auth/login
PaimonMultiplier.Gameserver	Game logic engine — KCP transport on :22101
PaimonMultiplier.Common	Shared assets & crypto utilities
PaimonMultiplier.Protocol	~590 protobuf definitions, CmdType & Retcode mappings
PaimonMultiplier.Kcp	Self-contained KCP reliable-UDP implementation
