Regenerator2000, developed by Ricardoquesada, is an interactive disassembler specifically for the 6502 CPU found in Commodore 8-bit computers. Built primarily with Rust, it functions as an MCP server tool, enabling AI assistants to programmatically interact with the disassembler. This cross-platform utility supports Linux, macOS, and Windows, offering a powerful environment for reverse engineering and code analysis of vintage systems. It connects directly to the VICE C64 emulator for live debugging capabilities.

What does Regenerator2000 connect to?

Regenerator2000 functions as an MCP server, designed to interact with AI clients such as Antigravity or Claude Code. It also establishes a direct connection to the VICE C64 emulator, allowing for live debugging sessions. This integration enables users to inspect CPU registers, memory states, set breakpoints, and step through code directly within an emulated Commodore 8-bit environment. The server supports both HTTP and stdio transport modes for client communication.

Core features and tools

The MCP Server component of Regenerator2000 exposes several capabilities. These include Tools for disassembly manipulation, memory search, block operations, and Resources for accessing binary data and views. It also bundles analysis skills that automate block classification, routine tracing, and symbol naming. These integrated skills allow AI assistants to perform initial analysis passes, significantly speeding up the reverse engineering process by automating repetitive tasks.

Who is it for?

Regenerator2000 targets developers, reverse engineers, and enthusiasts focused on 6502-based systems, particularly Commodore 8-bit computers. It also serves those interested in applying AI to reverse engineering challenges. The tool supports both manual, keyboard-centric code exploration and AI-driven analysis. It is ideal for individuals needing to analyze, debug, and understand vintage machine code. Skip this if you are not working with 6502 CPU architecture or Commodore 8-bit systems.

How to get started

No credentials are required for basic use. When using the regenerator2000-template repository for AI agents, it comes pre-configured with all the required skills and agent permissions. The MCP server supports HTTP and stdio transport modes for communication.

Use cases

• Manual Analysis: Interactive, keyboard-centric exploration to navigate code, define data, label subroutines, and add comments to refine disassembly.
• Automated Analysis: AI assistants drive the disassembler programmatically to analyze entire programs, classify blocks, trace routines, and name symbols.
• Combined Workflow: Users can employ AI for an initial analysis pass and then interactively refine the results.
• Live Debugging: Connect to the VICE emulator to inspect registers, memory, set breakpoints, and step through code.

Regenerator2000 offers a specialized disassembler for 6502-based Commodore 8-bit systems, uniquely combining interactive analysis with AI assistant integration. Its ability to connect with the VICE C64 emulator provides essential live debugging features. The tool's cross-platform availability and multiple distribution methods make it accessible. Try using its automated analysis skills to classify blocks and trace routines in a new 6502 binary.
