A collection of gate-level simulators for the original Game Boy (DMG-01), including GateBoy, which was reverse-engineered from die shots of the original chip, and LogicBoy, a faster C++ translation with bit-identical behavior. It also includes MetroBoy and related tools for hardware-level exploration of the Game Boy.

Use cases

• simulate the original Game Boy at the gate level
• study how the DMG-01 chip works internally
• run a cycle-accurate Game Boy hardware simulation
• verify Game Boy emulator behavior against hardware-level simulation
• explore reverse-engineered schematics of the Game Boy CPU
• run Game Boy test ROMs against a hardware-accurate model

When to choose

• you need hardware-accurate, gate-level Game Boy simulation
• you are researching or reverse-engineering the original Game Boy hardware
• you want to validate an emulator against a bit-accurate reference model
• you are studying digital logic design using a real chip as an example

When to avoid

• you just want to play Game Boy games at full speed
• you need a lightweight or fast emulator for casual use
• you need a general-purpose Verilog simulator or HDL toolchain
• you need support for Game Boy Color or newer hardware
