ArchaicFixFix (Fork)
by angleric
ArchaicFixFix (Fork) backports lighting and culling fixes and tweaks to Minecraft 1.7.10 through Forge.
What it does
The mod applies bugfixes and optimizations to Minecraft 1.7.10. It backports the Phosphor lighting engine, which corrects many lighting problems present in vanilla. Villagers no longer lock their trades after a restock, and new worlds use a modern naming scheme in which each world is called New World n instead of appending names continuously.
An optional occlusion culling can raise frame rates; it is disabled by default and can be turned on in the config file. Some other tweaks are configurable as well, and the config file is the place to learn what each one changes. The fork partially fixes the issue tracked as MC-2025, with the full fix still in progress.
The mod requires UniMixins, which must be installed alongside it. It works with OptimizationsAndTweaks. Files are published for Forge on 1.7.10 only, with the latest file v0.7fork10 dated 2025-11-30. The code is MIT licensed and the project is not open source under a copyleft license. Servers that run it need every player to install it too.

Use cases
Who it’s for: Players and server owners who keep a Minecraft 1.7.10 Forge setup and want lighting, villager and world naming fixes. Both the server and each player need the mod, since the environment is client and server.
How it compares
OptimizationsAndTweaks is also a client and server mod for 1.7.10 on Forge, but it is licensed under the GNU General Public License v3.0 only and is open source. Entity Culling Unofficial targets 1.7.10 on Forge as well, yet it is client-side only and uses the MIT License without being open source. Phosphor Legacy Forge covers 1.8.8 – 1.11.2 instead, and either side can run it, and neither needs it.
