sidwizard-driver 0.4.1

Python automation harness for driving SID-Wizard inside asid-vice — captures per-frame SID register writes from the real 6502 player.

sidwizard-driver

Python harness that drives SID-Wizard inside asid-vice and captures per-frame SID register writes from its real 6502 player. Output is a deduplicated (frame, reg, value) CSV — ground truth for verifying pure-Python SWM players like pysidwizard.

Built on vice-driver.

Install

pip install sidwizard-driver

Requires Docker (or compatible) and the asid-vice:latest image — see anarkiwi/asid-vice.

The SID-Wizard editor disk is fetched on demand from CSDB and cached under ~/.cache/sidwizard-driver/ (override with --d64 <path> or XDG_CACHE_HOME). Pre-fetch:

python -m sidwizard_driver.fetch

Usage

Boot smoke:

python -m sidwizard_driver.smoke

Capture a tune to CSV:

python -m sidwizard_driver.capture --swm tune.swm --frames 1500 --out tune.csv

Dump per-frame player ghost-register state:

python -m sidwizard_driver.ghost_dump --swm tune.swm --frames 60 --annotate --out ghost.csv

CSV schema

capture emits frame,reg,value (integers). Frame 0 is the first player tick after F1. reg is the SID register offset (0..0x18). Consecutive writes of the same value to the same register are collapsed.

ghost_dump emits frame,addr,value (with optional label column). Each frame yields rows for the per-voice zero-page block ($10..$80) plus six additional rows:

• Three for the filter-program self-modifying operand bytes — labelled FLTCTRL / FLTPOSI / CWEPCNT. These live in the loaded player code ($1xxx) and let downstream tools reconstruct SID-Wizard's per-frame filter-table position + sweep counter, which are NOT in zero page.
• Three for the per-voice DETUNER bytes (DETUNER_v0 / v1 / v2). DETUNER is in the CONST_VAR ZP region that INIPVAR doesn't clear; its base address varies by build, so it's discovered from the WRPITCH adc DETUNER,X operand and captured per voice.
