Reads real flash bytes from a target AVR chip through a Reader board running the ISP protocol, and shows the genuine Intel HEX, disassembly, and embedded strings. Nothing here is simulated.
What this does and doesn't do: this reads raw compiled bytes off the chip and decodes them into real AVR instructions where possible. It cannot recover your original variable names, comments, or C++ structure — that information is discarded at compile time and no tool can bring it back.
