OpenComputers 1.9.3 for Minecraft 1.21.1

New Features

• Added three tiers of Solid State Drives.

  • SSDs provide 4 MB, 8 MB, and 16 MB of storage.
  • SSDs are faster, silent, and consume less power than equivalent hard drives.
  • Managed and unmanaged modes are supported.
  • Unmanaged SSDs do not incur mechanical seek delays.
  • Added formatting recipes, configuration options, tags, and documentation.

• Added the Quad T2 Graphics Card.

  • Contains four independent Tier 2 GPUs in a single card slot.
  • Each GPU has its own component address.
  • Each GPU supports an 80×25 resolution, 16 colors, and three full-screen VRAM buffers.
  • The card consumes four component slots.
  • Added its recipe, model, tooltip, tags, and documentation.

Fixes

• Fixed component persistence across world reloads.

  • Screens, keyboards, EEPROMs, upgrades, and other component state now persist correctly.
  • Robots resume functioning correctly after reloading a world.

• Fixed robot rendering crashes caused by the obsolete ExtendedWorldRenderer implementation.

• Restored historical loot disk / floppy registration behavior.

  • API-registered loot disks are once again added to registeredItems.
  • Removed the unnecessary server-side loot disk synchronization workaround.
  • Prevented OpenPrinter disks from being registered twice.

• Fixed multiple recipes referencing invalid or outdated piston tags.

  • Electronics Assembler
  • Disassembler
  • Disk Drive
  • 3D Printer
  • Net Splitter
  • Card Containers
  • Inventory Upgrade
  • Other affected recipes using the same piston tag

• Fixed native library handling.

  • Native libraries are now stored under opencomputers/natives.
  • Added cleanup of obsolete extracted native libraries.

• Fixed release/mod metadata issues affecting packaged builds.

• Fixed several stale version references left over from earlier port builds.

Integrations

• Verified OpenComputers integration initialization for:

  • Create
  • ComputerCraft / CC:Tweaked
  • Mekanism
  • Minecraft

• Added native OpenComputers support for Create's computer-controllable blocks.

  • Added support for kinetic components, train stations, train signals, track observers, display links, Nixie tubes, stickers, package logistics, and stock systems.
  • Create events are forwarded to connected computers as OpenComputers signals.
  • Added Lua conversion support for Create packages and package-address data.
  • Train stations support assembly control, station and train naming, schedules, route checks, and distance queries.
  • OpenComputers connections are recognized by Create's existing computer behavior system.

Additional Fixes and Improvements

• Fixed robot persistence across world reloads.

  • Robots now retain their components and inventory correctly.
  • Fixed an issue that could cause robots to randomly lose installed items.

• Integrated OpenPrinter directly into OpenComputers.

  • OpenPrinter functionality is now included as a native part of the mod.
  • Its disks and components are registered directly by OpenComputers.
  • Prevented OpenPrinter disks from being registered more than once.

• Fixed numerous OpenComputers API regressions introduced by the previous port.

  • Restored historical API behavior where the port had introduced incompatible or unexpected changes.
  • Improved compatibility with software and integrations built against the established OpenComputers API.

• Removed substantial amounts of unnecessary automated-porting cruft.

  • Removed redundant compatibility code, workarounds, and migration artifacts.
  • Simplified affected code paths to more closely match original OpenComputers behavior.

Rendering / Client

• Tablets now render in the player’s hand while inactive.
  • Active tablets continue to display their running screen.
  • Offhand rendering still needs additional sizing and positioning adjustments.
  • Fixed robot rendering regression.
  • Continued cleanup of Hoverboots item rendering.
  • Verified tablet and machine rendering behavior after recent changes.

Configuration / Balance

• Reworked proposed RAM defaults to avoid the excessively large 1.21.1 progression while remaining slightly more generous than legacy OpenComputers values.

• Added configurable SSD read and write power costs.

  • SSDs consume half the default read and write power of hard disk drives.

Cleanup

• Removed several unnecessary port-specific workarounds introduced during the 1.21.1 migration.
• Restored original OpenComputers API behavior where newer port logic had caused regressions.
