Yqloss Client (Mixin)
by Yqloss
Yqloss Client is a Forge utility mod for Minecraft 1.8.9 that is built on Spongepowered Mixin and rewrites features of the original client.
What it does
Yqloss Client is a client-side mod for the 1.8.9 Minecraft version, built with Mixin rather than registering as a Forge mod or using the Forge events API. Its author works from the 1.8.9 decompiled source code and has no experience with the architecture of newer releases, so the project stays limited to that version. The author notes that changes to Hypixel's version of 1.8.9 are part of the scope of its gameplay features.
The mod's user interface is drawn with NanoVG 2D GUI rendering, and the menus depend on OneConfig. The author states that switching to another 2D rendering library would mean rewriting the entire GUI, and that configurations were lost when moving between different legitimacy versions of the game. The project is open source under the GNU General Public License v2.0 only, and its source code and issue tracker are public. First published on 2025-03-04 and last updated on 2025-10-30, the latest Forge file is 2.1.0 for 1.8.9.
Only the client needs the mod, so servers run without it and players may join without installing it. Its libraries are placed in the libraries folder, and the author states that the bundled libraries keep compatibility and a better user experience in the same build.

What the author says
不会做高版本移植，因为： 我不会。我从来没有开发过高版本 Mod。我可以说对 1.8.9 的反编译源码了如指掌，但是对高版本一无所知 我主玩地牢，在主玩 1.8.9 的前提下，个人感觉高版本手感远不如低版本，不喜欢用高版本玩地牢 没有空余时间，没有开发动力，没有账号测试 OneConfig 库正在被重写，而本项目中包含许多关于 OneConfig 的黑魔法，重新适配略有难度 如果放弃 OneConfig 的话有两条路可以走：自己加载 NanoVG 或者选择其他 2D 渲染库并重写 GUI，显然哪个都不容易 Minecraft 从低版本到高版本的改动也较大，尤其是对于本项目这种从来没有考虑过高版本适配的…
