# Tag Team Wrestling (U)

## 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: 17,170 / 32,768 bytes (52.4%).
`make` assembles and verifies byte-identical to `rom.nes`.
