## Status
|
|
|
|
**Pass 3 complete; promoted.** `prg.s` is a traced disassembly with all
|
|
address-derived labels replaced, all `jsr`/`jmp` operands symbolic, hardware
|
|
registers named via `symbols.inc`, and `apply_symbols.py` reporting 0 residue.
|
|
Code coverage: 10,136 / 32,768 bytes (30.9%).
|
|
`make` assembles and verifies byte-identical to `rom.nes`.
