[Latest Version : OLDCRAFT V1.0]
Oldcraft is a pretty barebones modpack that brings back the nostalgic feel of Mincraft featuring 3 major mods:
From the Fog, by LunarEclipseStudios / / Brings in a working version of Herobrine that can stalk you, place signs, and much more https://modrinth.com/datapack/from-the-fog
Nostalgic Tweaks, by Adrenix / / Brings back old Minecraft beta and alpha features in a very configurable way https://modrinth.com/mod/nostalgic-tweaks
Modern Beta, by b3spectacled / / Lets you play on beta, alpha, and even indev world generations of minecraft. Includes farlands https://www.curseforge.com/minecraft/mc-mods/modern-beta/files/4496219
This mod also features very many optimization mods to make sure Minecraft runs at top performance, including but not limited to:
Iris Shaders, Fastload, Dashloader, FerriteCore, Memory Leak Fix, Sodium, &more
Recommend use the "Golden Days" resourcepack created by PoeticRainbow found at https://modrinth.com/resourcepack/golden-days if you would like old Minecraft textures and sounds
I have gotten pretty much everything out of this modpack that I wanted, oldschool playstyle and world gen with an actual Herobrine to haunt you. I don't plan on updating this pack further, feel free to download, modify, and redistribute as long as you do so within the original mod developers individual licenses and wishes.
Enjoy!
