설치

클라이언트 선택

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "geargrafx-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/drhelius/Geargrafx"
      ]
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "geargrafx-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/drhelius/Geargrafx"
      ]
    }
  }
}

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "geargrafx-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/drhelius/Geargrafx"
      ]
    }
  }
}

Cline 사이드바의 MCP Servers 아이콘 클릭 후 "Edit Configuration" 선택.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "geargrafx-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/drhelius/Geargrafx"
      ]
    }
  }
}

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "geargrafx-2",
      "command": "TODO",
      "args": [
        "See README: https://github.com/drhelius/Geargrafx"
      ]
    }
  ]
}

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

{
  "context_servers": {
    "geargrafx-2": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/drhelius/Geargrafx"
        ]
      }
    }
  }
}

context_servers에 추가. 저장 시 Zed가 핫 리로드.

claude mcp add geargrafx-2 -- TODO 'See README: https://github.com/drhelius/Geargrafx'

한 줄 명령. claude mcp list로 확인, claude mcp remove로 제거.

How to debug a PC Engine ROM with AI assistance using Geargrafx

👤 PC Engine homebrew developers and retro game researchers ⏱ ~30 min intermediate

언제 쓸까: You're developing or analyzing a PC Engine ROM and need to debug runtime behavior.

사전 조건

Geargrafx built with MCP support — Build from source following the GitHub README
A PC Engine ROM file (.pce or .sgx) — Your own homebrew ROM or a ROM you legally own

흐름

Connect and inspect

Connect to the Geargrafx MCP server. Show me the current HuC6280 CPU state and disassembly at the program counter.✓ 복사됨

→ CPU registers and disassembled instructions
Analyze sprite system

Inspect the VDC sprite table. How many sprites are active and what tiles do they reference?✓ 복사됨

→ Sprite attribute table with positions, tile indices, and flags

결과: Understanding of ROM execution and VDC hardware state for debugging.

함정

CD-ROM games require proper CUE/BIN setup — Ensure your CUE file paths are correct and all BIN tracks are present

함께 쓰기: filesystem

Learn PC Engine hardware architecture interactively

👤 Students and enthusiasts learning retro console hardware ⏱ ~45 min advanced

언제 쓸까: You want to understand the HuC6280 CPU, VDC graphics, and PSG audio systems.

사전 조건

Geargrafx with MCP server — Build from source

흐름

Explore the VDC

Step through the VBlank interrupt and explain how the PC Engine's VDC handles background scrolling and sprite rendering.✓ 복사됨

→ Annotated explanation of VDC register writes and their effects

결과: Hands-on understanding of PC Engine hardware internals.

함정

SuperGrafx has two VDCs which complicates analysis — Start with regular PC Engine games before tackling SuperGrafx titles

조합

다른 MCP와 조합해 10배 효율

geargrafx-2 + filesystem

Export debug data and memory dumps for documentation

Dump the VDC sprite table and tile data to files for analysis.✓ 복사됨

도구

이 MCP가 노출하는 것

도구	입력	언제 호출
pause/resume/step	none / step_count?	Control emulator execution
read_memory	address: int, size: int	Read emulator memory at any address
set_breakpoint	address: int	Set a CPU breakpoint
disassemble	address: int, count: int	Disassemble HuC6280 instructions
get_hardware_status	none	Get VDC, VCE, and PSG register states

비용 및 제한

운영 비용

API 쿼터: N/A — fully local
호출당 토큰: 100–500 tokens per debug command
금액: Free and open source (MIT license)
팁: Use targeted reads instead of full memory dumps.

보안

권한, 시크릿, 파급범위

자격 증명 저장: N/A

데이터 외부 송신: Fully local — no network calls

문제 해결

자주 발생하는 오류와 해결

MCP server not responding

Ensure Geargrafx was built with MCP support. Check the default port is available.

확인: Test the HTTP endpoint

CD-ROM game won't load

Verify CUE file references correct BIN paths. Try converting to CHD format.

확인: Check CUE file contents match actual BIN filenames

SuperGrafx ROM crashes

Only a handful of SuperGrafx games exist. Verify the ROM is actually an SGX title, not a regular PCE ROM.

확인: Check ROM header
