Contributed to the GregTech-Modern repository by implementing EMI integration for multiblock preview encoding, enabling accurate handling of multiblock previews within the EMI system. This work introduced a new recipe type, MultiblockInfoEmiRecipe, alongside the existing GTEmiRecipe, extending the mod’s workflow and future compatibility. Using Java and backend development skills, addressed pattern encoding reliability and maintainability, reducing manual workarounds for users. Additionally, improved the OpticalDataHatchMachine by enforcing data operation guards, ensuring energy is only consumed when appropriate and updating interfaces for multi-controller support. These targeted changes enhanced both user experience and system integrity within the modding environment.
