- **Corrected Zero Flag Behavior**: This update resolves a crucial issue where the zero flag, which resides in the accumulator, was not being set correctly following `ADD` and `SUB` instructions. However, it operated correctly after `LOAD` instructions. This inconsistency has been corrected to ensure uniform behavior of the `JZ` (Jump if the accumulator is Zero) instruction across different scenarios, enhancing both the accuracy and reliability of instruction execution.
