trace-address

What problem does it solve?

This Skill automates the process of tracing data addresses in 6502 Apple II game binaries, helping reverse engineers determine the purpose and assign meaningful labels to memory locations.

Core Features & Use Cases

• Address Reference Identification: Finds all references to a specified data address through Ghidra cross-references and raw byte pattern searches.
• Contextual Analysis: Disassembles surrounding code to understand how data addresses are used, whether for reading, writing, or computation.
• Use Case: A researcher wants to understand what the memory location $5A74 stores in the game binary, revealing whether it holds a variable, pointer, or control data.

Quick Start

Analyze a data address in the game binary by executing /trace-address $XXXX, then review the identified references and labels for further reverse engineering.
