Nostalgic Tweaks
Nostalgic Tweaks restores alpha, beta and post-release gameplay elements that Minecraft Java Edition later removed or changed, as a set of toggleable options.
What it does
Each tweak can be switched on or off in the config menu. The tweaks cover older light engines, fog rendering, sky and void colors, 2D floating items without diffused lighting, mob spawning, combat mechanics, classic game screens and C418 music. Over 400 tweaks exist as of 2.0.0-Beta 9, and more are planned. Tweaks that conflict with non-modded servers are disabled automatically.
The mod is aimed at players who want to replay older versions of the game, and at those who prefer a different aesthetic or gameplay style. Architectury API and Fabric API are required, so both must be installed with it on the loaders that need Fabric API. Nostalgic Tweaks is open source under the GNU Lesser General Public License v3.0 only, and files cover 1.18 – 1.21.1 across Fabric, Forge and NeoForge.
The config menu opens with the O key in game or on the title screen, and the hotkey can be changed. Some visual problems come from other mods, and the author advises adjusting their settings. Optifine is closed source and known to clash with some tweaks, which are tagged in the config menu. Sodium is officially supported.

Hotkey menu access

How it compares
Nostalgic Fishing is open source under the MIT License and only the server needs it; clients can join without it, with files for Fabric, Forge, NeoForge and Quilt. Classic Beta Biomes is not open source under the MIT License, runs on client or server, and targets 1.16.5 – 1.21.5 for Fabric, Forge and NeoForge. Nostalgic Tweaks itself covers 1.18 – 1.21.1 and works with either side optional.
