FAQPage Schema
How do I analyze 6502 disassembly routines to understand what they do?▼

To analyze 6502 disassembly routines, you need to examine code flow, cross-references, and memory access patterns. This process identifies the routine's purpose, inputs, outputs, and side effects, making reverse engineering much more efficient.

How does routine analysis identify the purpose of unfamiliar Commodore 64 assembly code?▼

Routine analysis identifies code purpose by leveraging platform-specific knowledge like C64 hardware registers and KERNAL routines. This context helps determine whether a block of code is a sprite rendering routine, sound driver, or input handler.

Can I rename labels and add comments while reverse engineering 6502 code?▼

Yes, you can rename labels and add comments while reverse engineering 6502 code. Documenting findings directly within the disassembly helps clarify routine functionality and supports better code flow comprehension.

What is the best way to determine the inputs and outputs of a 6502 routine?▼

The best way to determine 6502 routine inputs and outputs is by examining memory access patterns and cross-references. This analysis maps how data moves through the routine and identifies side effects on hardware registers.
