# ReplayMod for OneClient 1.8.9

> Get ReplayMod on Legacy Fabric / Ornithe 1.8.9 clients, such as the OneClient.

Recently I started using Polyfrost's [OneClient](https://polyfrost.org/projects/oneclient) and I reallyyy enjoy it! Coming from my own forge modpacks, the performance of OneClient over forge or even [Lunar Client](https://www.lunarclient.com/) or [Badlion](https://www.badlion.net/) is insane. And it's fully opensource, so we can know they don't steal our data like Lunar does. 

I couldn't find [ReplayMod](https://github.com/replaymod/replaymod) for it though, which I really enjoy having on when playing. The mod has no builds for LegacyFabric. And nobody has made a fork yet that ports it to it. So I did it!

## What was done?

We implemented support for Legacy Fabric 1.8.9 to ReplayMod 2.6.28 — the latest mod version. There is no Fabric API dependency, so it works with Ornithe based clients such as OneClient.

All Forge API calls have been replaced with Fabric, which is why some features e.g. payload based server-side mod feature disabling are not implemented yet (there's no FML handshake). 

## Note

It is in very early development, so [let me know](https://marcloud.net/discord) if you find any issues or something hasn't been implemented yet!
