How to Set Up and Use Regenerator2000
Regenerator2000 is an interactive disassembler for the MOS 6502 CPU, purpose-built for reverse-engineering Commodore 8-bit software (C64, C128, VIC-20, Plus/4, PET). It ships both a full-featured TUI with undo/redo, cross-references, and VICE debugger integration, and an MCP server interface that lets AI assistants drive disassembly tasks programmatically — automating routine tracing, block classification, and symbol naming that would otherwise require hours of manual analysis.
Prerequisites
- Rust toolchain installed (cargo available in PATH) to build from crates.io
- A Commodore binary file to analyze (PRG, CRT, D64, D71, D81, T64, or VSF format)
- An MCP-compatible client such as Claude Desktop or Claude Code
- Optional: VICE emulator running with remote debugging enabled if you want live breakpoint integration
Install Regenerator2000 via Cargo
Install the latest stable release from crates.io using Cargo. This compiles the Rust binary for your platform and places it in ~/.cargo/bin.
cargo install regenerator2000Verify the installation
Confirm the binary is on your PATH and check the version. The binary must be reachable for MCP clients to launch it.
regenerator2000 --versionStart the MCP server in stdio mode
Run the server in stdio mode so MCP clients can spawn and communicate with it over standard input/output. Use HTTP mode (--mcp-server, port 3000) for remote or multi-client setups.
regenerator2000 --mcp-server-stdioConfigure your MCP client
Add the server to your Claude Desktop or Claude Code configuration file. The client will automatically spawn the process when needed.
Load a binary for analysis
Open a Commodore binary through the TUI or pass it as an argument. Supported formats include PRG programs, CRT cartridges, D64/D71/D81 disk images, and T64 tape images.
regenerator2000 game.prgUse MCP tools for automated reverse-engineering
Once connected, AI assistants can invoke MCP tools to perform disassembly manipulation, memory searches, block classification, routine tracing, and symbol naming without manual TUI interaction.
Export the annotated assembly
Export the disassembly in your preferred assembler format (64tass, ACME, ca65, or KickAssembler) or as HTML documentation once analysis is complete.

Client configuration
Add Regenerator2000 to claude_desktop_config.json to enable the MCP server. The binary path must be absolute or on PATH.

}Prompts to try
Example prompts you can use once the MCP server is connected in your AI client.
- "Load game.prg and trace all subroutines starting from the entry point at $0801"
- "Search memory for the byte sequence EA EA EA and classify those blocks as NOP sleds"
- "Rename the subroutine at $C000 to 'init_sprites' and add a comment explaining what it does"
- "Export the fully annotated disassembly as 64tass-compatible assembly to output.asm"Troubleshooting Regenerator2000
Command not found after cargo install
Ensure ~/.cargo/bin is in your PATH. Add 'export PATH="$HOME/.cargo/bin:$PATH"' to your shell profile and reload it.
MCP client cannot connect to the server
Verify the binary path in your config is correct. Run 'regenerator2000 --mcp-server-stdio' manually and check for startup errors. If using HTTP mode, confirm port 3000 is not blocked by a firewall.
VICE debugger connection fails
Start VICE with the remote monitor enabled: x64 -remotemonitor -remotemonitoraddress ip4://127.0.0.1:6502. Then pass --vice 127.0.0.1:6502 to regenerator2000.
