Universal Adaptive Backporter (UAB)

Modern Minecraft. Classic Foundations.

Universal Adaptive Backporter (UAB) brings content from Minecraft 1.8 through 1.21.11 into Minecraft 1.7.10 and 1.12.2, adapting modern blocks, items, mobs, biomes, structures, equipment, and gameplay mechanics to work within classic Forge environments.

Originally developed from Et Futurum Requiem, UAB has evolved into an extensive modern-content backport focused on survival functionality, configurability, world compatibility, and native integration.

Rather than simply introducing modern content as decoration or Creative-only items, UAB aims to make newer features obtainable, functional, and meaningfully integrated into classic Minecraft survival.

HOW DO I INSTALL THIS?

UAB supports Minecraft Forge 1.7.10 and 1.12.2. Each version has different dependency requirements. Only install the dependencies listed for your Minecraft version.

Minecraft 1.7.10

Requirements:

• UniMixins, including the GTNH Mixins module

Minecraft 1.12.2

Requirements:

• MixinBooter 11.18 or newer

Installation Instructions

Install UAB and the dependencies for your Minecraft version into your mods folder.

Dedicated servers must also install UAB and its corresponding dependencies.

Important: Remove existing Et Futurum Requiem or Et Futurum Requiem Reforged installations before installing UAB. These projects share technical identities and cannot be installed simultaneously. DO NOT TRY IT.

Some modern assets are provided through the included Minecraft AssetDirector integration and may require an initial download.

Back up existing worlds before upgrading.

Modern Mobs & Wildlife

Discover a massive collection of modern Minecraft creatures, including:

• Aquatic: Cod, Salmon, Tropical Fish, Pufferfish, Dolphins, Turtles, Drowned, Axolotls, Glow Squid, and Nautiluses.
• Passive & Neutral: Bees, Foxes, Pandas, Goats, Frogs, Allays, Camels, Sniffers, Armadillos, Parrots, and Happy Ghasts.
• Hostile: Pillagers, Ravagers, Piglins, Hoglins, Wardens, Breezes, Bogged, Creaking, and newer undead variants.
• Additional Variants: Modern Wolf coats and sounds, climate-dependent animal appearances, colored eggs, and additional mob equipment.

Mobs include adapted implementations of their spawning, combat, breeding, drops, equipment, and unique interactions.

Raise and harness Happy Ghasts, tame Parrots, explore underwater ecosystems, encounter Trial Chamber enemies, and discover newer creatures throughout the world.

Modern AI, movement, and animations are adapted where necessary to fit the older engines.

Expanded World Generation & Exploration

Explore an expanded world featuring:

• Modern surface, mountain, ocean, and optional Nether biomes.
• Ocean Monuments, Shipwrecks, Ocean Ruins, and Buried Treasure.
• Ruined Portals, Bastion Remnants, and Pillager Outposts.
• Igloos, Woodland Mansions, and Trail Ruins.
• Ancient Cities, Trial Chambers, and archaeology sites.
• Outer End islands, End Cities, End Ships, and End Gateways.
• Optional expanded 128-Stronghold generation on Minecraft 1.7.10.
• Modern vegetation, copper features, and biome-specific wildlife.

Structures are adapted for legacy world heights and terrain generation, with persistent structure data and safeguards against duplicated loot, unwanted regeneration, and interference with existing terrain.

Compatibility adaptations are also included for selected dimension and world-generation mods, including Enderlicious and Netherlicious.

Existing chunks are not automatically regenerated. Explore new terrain to discover newly generated features.

Modern Combat, Equipment & Progression

Modern survival progression extends well beyond additional crafting materials.

• Maces: Devastating falling smash attacks with Density, Breach, and Wind Burst enchantments.
• Shields: Directional blocking and axe disabling on Minecraft 1.7.10, with native shields retained on 1.12.2.
• Spears: Modern spear combat and the Lunge enchantment.
• Netherite: Equipment upgrades, Smithing Templates, and Netherite Horse Armor.
• Copper Equipment: Copper tools, armor, and horse equipment.
• Elytra: Modernized flight interactions and Firework Rocket boosting.
• Armor Trims: Customizable armor appearances with obtainable templates and materials.
• Archaeology: Suspicious blocks, Brushes, Pottery Sherds, and Decorated Pots.

Modern equipment uses native combat, enchanting, durability, and inventory systems wherever possible.

Functional Blocks, Workstations & Redstone

UAB introduces functional modern blocks rather than decorative substitutes.

• Crafters: Redstone-powered automatic crafting with configurable slots and hopper integration.
• Grindstones: Repair equipment, remove enchantments, and recover experience.
• Lecterns: Read books, turn pages, and generate redstone signals.
• Chiseled Bookshelves: Store books individually and interact with comparators.
• Shelves: Store items and swap hotbar contents through redstone.
• Campfires: Cook food, create signal smoke, and calm nearby bees.
• Bells: Ring manually or through projectiles and redstone.
• Calibrated Sculk Sensors: Filter vibrations using redstone frequencies.
• Sculk Catalysts: Spread sculk using experience from mob deaths.
• Copper Chests: Functional storage with oxidation, waxing, and Copper Golem integration.

Additional systems include Smokers, Blast Furnaces, Stonecutters, Looms, Cartography Tables, Composters, Barrels, and other modern workstations.

Expanded Survival Mechanics

Modern survival introduces new ways to explore, build, and manage resources.

• Bundles: Portable weighted storage with all 16 color variants.
• Scaffolding: Quickly build climbable structures and platforms.
• Powder Snow: Freezing, sinking, leather protection, and bucket interactions.
• Respawn Anchors: Set charged respawn points within supported Nether environments.
• Lodestones: Bind Compasses to specific locations.
• Recovery Compasses: Locate your last recorded death position.
• Spyglasses: Zoom into distant terrain and objects.
• Beekeeping: Harvest honey, use dispensers, and interact with functional hives.
• Copper Oxidation: Weather, wax, scrape, and maintain copper blocks and equipment.
• Rooted Dirt & Hanging Roots: Additional growth, farming, and decoration mechanics.

New recipes, loot sources, and crafting dependencies integrate these features into legacy survival wherever practical.

Modern Vegetation & Building Materials

Expand your builds with hundreds of modern blocks and decorations spanning multiple Minecraft updates.

Highlights include Cherry and Pale Oak wood families, Bamboo building materials, Mangrove wood, expanded Copper and Tuff blocks, Hanging Signs, decorative Pots, Candles, modern flowers, and additional stone variants.

The Spring to Life update also introduces Leaf Litter, Wildflowers, Firefly Bushes, Cactus Flowers, Fallen Logs, and other natural decorations.

Additional animal appearances and biome-dependent variants bring modern environmental diversity to classic worlds.

Highly Configurable

UAB uses a unified configuration system:

config/uab.cfg

Configuration options are organized by the Minecraft update that introduced each feature.

• Enable or disable entire update categories.
• Configure individual blocks, items, mobs, structures, and mechanics.
• Adjust applicable mob spawn weights and group sizes.
• Customize world generation and structure availability.
• Control optional integrations and client-side preferences.
• Preserve existing settings when updating configurations.

The configuration offers over 350 distinct feature switches, providing extensive control for players and modpack creators.

Existing recognized Et Futurum Requiem settings can be imported automatically, with migration backups retained.

Some systems, including automatic Crafters, are disabled by default and can be enabled individually.

Designed for Legacy Modpacks

UAB prioritizes compatibility with classic Forge modding ecosystems.

• Supports Minecraft 1.7.10 and 1.12.2.
• Preserves existing Et Futurum technical identities and saved-world data.
• Supports dedicated servers and multiplayer.
• Provides optional integrations with NEI, Waila, CraftTweaker, Iron Chests, and selected legacy mods.
• Includes compatibility adaptations for Enderlicious, Netherlicious, and other supported environments.
• Retains native world-generation providers, terrain systems, and inventory ownership where possible.
• Avoids unnecessary replacement of Minecraft's underlying engines.
• Does not require HogUtils, FastUtil, GTNHLib, or GTNHExtLib.

UAB is intended to coexist with existing modpacks rather than unnecessarily replacing core legacy systems.

Compatibility & Limitations

UAB adapts modern Minecraft content to older engines rather than replacing them entirely.

Consequently, some mechanics differ from their modern Java Edition counterparts. UAB does not introduce a complete modern swimming or waterlogging engine, expanded world height, universal modern cave generation, or a complete modern combat overhaul.

Certain mob behaviors, animations, structure placements, and interactions use legacy-compatible implementations. Some features and optional integrations remain under development.

Supporting content through Minecraft 1.21.11 does not imply perfect feature parity with every modern release.

The goal is a coherent, functional modern-survival experience built on classic Minecraft foundations.
