Remielle

segs

Remielle is a Zenless Zone Zero server emulator that prioritizes efficiency, stability and correctness.

Remielle makes heavy use of comptime semantics in order to ensure logic correctness on the level of the type system, this eliminates most common bugs and pitfalls that occur in most implementations.

We maintain our own implementation of Io interface, RemiellIo. It's based on coroutines and supports both Linux and Windows. It utilizes high-end APIs these systems offer (Linux: io_uring; Windows: I/O Completion Ports).

We also maintain an in-house implementation of protobuf serializer and compiler, rmpb. This allows us to avoid a dependency on, for example, protoc. The replacement fulfilling the needs of this server is just ~600 lines of code!

Requirements

To build Remielle from sources you need:

For use with the game client, the client patch is required: vortex (a replacement is being worked on)

Currently supported client version: CNBetaWin3.1.3, it can be found in our discord server

Steps to compile and run

Linux:

# git(1) must be available in the $PATH
git clone https://git.xeondev.com/remielle/remielle.git
cd remielle
. ./envrc # The `envrc` script will setup the zig compiler for you.
zig build serve-all

Windows (powershell):

# git(1) must be available in the $PATH
git clone https://git.xeondev.com/remielle/remielle.git
cd remielle
./envrc.ps1 # The `envrc.ps1` script will setup the zig compiler for you.
zig build serve-all

Configuration

The configuration of Remielle is done by editing dpsv/config.zon and gamesv/config.zon and (re)compiling the source code.

Some of the server behavior can be also overridden through command line options.
