About this project

State of Development
This mod is still being worked on. Updates are slow to come out since myself and the other volunteer maintainers are super busy with personal matters. If you are a developer and are interested in helping us out with updates then please join the Discord and let us know! The v2.0 update will be released for Minecraft 1.20.1 and 1.21.1. A rewrite of the mod (v3.0) will be made for whatever Minecraft version that modders consider to be the next LTS. I cannot provide any potential release dates at this time. Thank you for the patience!
Description
Inspired by Exalm's Old Days mod, Nostalgic Tweaks brings back a plethora of classic, alpha, beta, and post-release lost or changed gameplay elements. This mod is intended for nostalgic enthusiasts who want to relive the glory days of Minecraft Java edition by tweaking the mod to their nostalgic preference, or for those who want to give the game a new aesthetic and gameplay style.
Some of the major nostalgic tweaks included are old classic and pre-beta 1.8 light engines, old fog rendering, old sky and void colors, 2D floating items with disabled diffused lighting, old mob spawning, old combat mechanics, old game screens, old C418 music, and so much more! There are currently over 400+ nostalgic tweaks as of 2.0.0-Beta 9 with more on the way!
For the best nostalgic experience, I recommend using the Golden Days resource pack by PoeticRainbow, or the Programmer Art Continuation Project resource pack by mzov. Golden Days comes with an abundance of nostalgic packs, such as an alpha and picture perfect pack which coincides wonderfully with Nostalgic Tweaks. Additionally, use the Moderner Beta mod by BlueStaggo for nostalgic terrain generation.
Configuration
To open the mod's config menu, press O for "Old" while in-game or at the game's title screen. This hotkey can be changed in the vanilla controls menu or in the mod's config menu. If you have Mod Menu installed for Fabric, or you are using Forge or NeoForge, then you can also access the configuration screen through the Mods button.
Each tweak will have tags above their names in the config menu. Each tag identifies different aspects of each tweak. You can hover your mouse over each tag to see more information as a tooltip. You can favorite the tweak, see its status, modify the client/server value, save, undo, reset, and modernize a tweak within its configuration box.
Compatibility
This is a list of commonly reported problems and their potential solutions:
- If you are using the Better Clouds mod, then you may experience issues. If so, in Better Cloud's options, change Fog Distance Factor to 2.00x.
- If you are experiencing issues with chunks not updating light changes (usually caused by mod conflicts), then disable the
Round Robin Chunk Relightingtweak. This can be found underEye Candy > Lighting Candy > World Lighting > Light Engine. - Optifine is known to cause problems. It is a closed source mod, so it is very difficult to support. Tweaks that are known to be impacted by Optifine are tagged in the config menu.
- Sodium & Embeddium are officially supported.
If you experience a crash or come across a compatibility issue, please let me know! It is best to report compatibility issues on our GitHub issue page for better tracking.
