Added and refactored several instructions and memory operations, improving accuracy and functionality for emulation. Introduced new dependencies (`serde_json`, `glob`) and submodule for test framework integration. Enhanced debugging, flat RAM handling, and opcode parsing while fixing multiple calculation and flag-setting issues.
Introduce clearer boot ROM handling and streamline `execute_next_instruction` for better readability and accuracy. Add program counter (`pc`) updates within each instruction, improving program flow consistency.
Introduced `GameRom` struct and implemented support for MBC1 cartridges, including ROM and RAM banking. Modified `MemoryBus` and `CPU` to use `GameRom` for cartridge interactions, replacing raw game ROM handling. Added logic to load, read, and write cartridge memory based on type and address.
Introduced symbol files for various Game Boy systems (CGB, AGB, MGB, SGB) to define boot sequences and functionalities. Included CPU instruction behavior tests, with detailed coverage of standard operations and interrupt handling. Added documentation for test execution and internal framework operations.
This commit sets up a foundational CPU simulation with registers, a memory bus, and an initial instruction set implementation in Rust. It includes operations like ADD, SUB, AND, and bit manipulations, as well as basic project configurations through Cargo and IDE settings.
