AE2: Back to Life
An unofficial port of Applied Energistics 2 19.2 (Minecraft 1.21.1) to Minecraft 1.12.2 (Forge): the same items, blocks, recipes, textures and mechanics as the modern AE2, on 1.12.2.
Not made or supported by the Applied Energistics 2 team. Please report problems with this port on GitHub, not to the AE2 developers.
Features
- ME networks with channels, controllers, cables and P2P tunnels
- Item and fluid storage cells, drives, ME chests and terminals
- Autocrafting: crafting CPUs, pattern providers, molecular assemblers, pattern encoding and pattern access terminals
- Certus quartz growth with budding quartz, the charger, the inscriber and meteorites with inscriber presses
- Spatial storage, wireless terminals, portable cells, facades, the memory card and the network tool
- In-game guide (Patchouli, English and Russian)
- Integrations: JEI, The One Probe, Hwyla
- 1.12.2 has no vanilla copper, so the mod adds its own copper ore and ingot (can be turned off in the config)
Requirements
- Minecraft 1.12.2
- Forge 14.23.5.2847 or newer
- Optional: JEI, The One Probe or Hwyla, Patchouli
Not compatible with Applied Energistics 2 rv6 / AE2 Unofficial Extended Life or their addons. Use one of them, not both.
Beta
The port is playable but young. Back up your worlds and report bugs in the issue tracker.
