Brings Gearsystem's Sega Master System, Game Gear, and SG-1000 emulator into Claude's reach with debugging and inspection tools. You get execution control to step through Z80 instructions, memory inspection to read RAM and VRAM, hardware status checks for the VDP and PSG, and rewind capabilities to move backward through execution. Reach for this when you're reverse engineering classic Sega ROMs, debugging homebrew code, or analyzing how games interact with the hardware. The emulator itself is production grade with accurate Z80 and VDP emulation, support for cartridge mappers and save states, and a built-in debugger with disassembly. This connects those internal debugging hooks to Claude so you can ask questions about game state, memory patterns, or execution flow without manually inspecting hex dumps.
