About:
1:1 Beta is a modpack aiming for near 100% parity between modern Minecraft versions and beta 1.7.3. It accomplishes this by utilizing a variety of mods, datapacks, and resourcepacks to revert Minecraft back to beta! This modpack will only be made available for newer versions of the game if supported mods are updated to those versions. 1:1 Beta was made with the intention of allowing an easy and seamless player experience back into beta minecraft, with the added customization that modern game versions provide. So feel free to add Vivecraft for VR support, a LAN extension mod for multiplayer, or to tweak the existing mods to your liking!
What Makes This Pack Special? Aren't There Already Modpacks That Do This?
Most modpacks that try to do this recreate most of the beta features (like world gen, visuals, etc.), but are either missing some things or intentionally incorporate newer features. As previously mentioned, this modpack is different in that it completely disables as many as are possible non-beta 1.7.3 features, with the exception of some objective annoyances and bugs from back then.
Notes:
How To Generate Beta Worlds:
- Singleplayer > Create New World
- World > World Type: Moderner Beta
- Customize > Chunk Provider Settings
- Generate Deepslate: OFF > Save Settings > Done
- More > Datapacks > add "moderner_beta/reduced_heights" to the right > Done

Resourcepacks:
The resource/texture pack load order should be enabled by default, however please double check on first load of the modpack that programmer art is loaded last.
Java:
This modpack requires the use of Java 17. If you don't have it, I recommend getting your OS' respective version from here and installing it.

- Deepslate ores, stone variants, quartz in nether still generate
