# Ms Pac-Man (Namco) (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: 10,136 / 32,768 bytes (30.9%).
`make` assembles and verifies byte-identical to `rom.nes`.

## Power-on flow

RESET enters at `$FFF7`:

    jmp Sub_C004                   ; CPU:$FFF7 PRG:7FF7  4C 04 C0
    .byte $07, $C1, $F7, $FF, $98, $C1  ; CPU:$FFFA PRG:7FFA  07 C1 F7 FF 98 C1

NMI handler at `$C107`:

    pha                            ; CPU:$C107 PRG:4107  48
    txa                            ; CPU:$C108 PRG:4108  8A
    pha                            ; CPU:$C109 PRG:4109  48
    tya                            ; CPU:$C10A PRG:410A  98
    pha                            ; CPU:$C10B PRG:410B  48
