This repository implements a Field-Programmable Gate Array (FPGA) based emulator for Nintendo Game Boy and Game Boy Color systems, specifically targeting the Analogue Pocket handheld console. The design consists of hardware description language (Verilog/VHDL) modules that replicate the original hardware components including a Z80-compatible CPU core (T80), memory controllers, video display subsystem, four-channel audio processing unit, input handling, cartridge interface with various Memory Bank Controller (MBC) implementations, save state functionality, and real-time clock support. The architecture follows a modular approach with clear separation of concerns between subsystems, interconnected through well-defined interfaces. The project demonstrates significant effort in achieving hardware-level accuracy while incorporating modern features like save states, fast forwarding, and custom palettes. While the codebase shows signs of active maintenance and ongoing development, it remains tightly coupled to the target FPGA platform (Cyclone V) and associated Intel/Altera toolchain, which limits immediate portability to other hardware platforms.
