Analyze unknown 6502 memory addresses by examining their cross-references and usage patterns. The skill determines whether an address functions as a hardware register, pointer, flag, counter, or state variable, using platform context and usage heuristics to rename and comment symbols.

In C64 assembly code, an address like $D020 is identified as the VIC-II border color register. The skill leverages platform-specific hardware knowledge to identify such registers and automatically renames and comments the symbols for improved code readability.

Yes, you can automatically rename labels and add comments to 6502 assembly code. After determining a symbol's purpose by examining cross-references and platform context, the skill renames the symbol and adds explanatory comments to improve code readability.

Yes, symbol analysis supports hardware register identification for retro platforms. It leverages platform-specific knowledge, such as C64 hardware registers, and cross-reference data to infer the roles of symbols based on platform context and usage heuristics.

Cross-references help with reverse engineering 6502 code by revealing how and where a memory address or label is accessed. Examining these usage patterns allows the identification of flags, counters, pointers, and state variables to determine the symbol's purpose.
