Geargrafx vs Charles-mcp

Geargrafx: Geargrafx is a highly accurate cross-platform emulator for TurboGrafx-16/PC Engine/SuperGrafx/PCE CD-ROM² systems. It runs on multiple desktop platforms and RetroArch, featuring an embedded MCP server for AI-assisted debugging. The emulator supports a wide range of features including save states, CD-ROM support, and extensive debugging tools.; Charles-mcp: Charles MCP Server bridges Charles Proxy with MCP clients, enabling AI agents to read live traffic incrementally, analyze recorded sessions with structured summary-first output, and drill down into details. It supports real-time capture, history analysis, and a reverse engineering toolchain for decoding, replay, and signature discovery, all with token-budget optimized responses.
