(DRM-bound content) registering the CID in `07GTCHLG.DAT` and binding the license to the device key. + +SonicStage performs all of this opaquely. **There is no documented standalone path to write the database from outside SonicStage.** Community tools (e.g. `qmtwalkman`, "OMGTOOL") existed but are abandoned and tightly coupled to specific SonicStage versions. + +## Quirks & Limitations + +- **Not user-syncable as plain mass storage.** Files copied into `OMGAUDIO/10FXX/` without corresponding database entries are invisible to the device's library browser. Files in any other directory (root-level, `MUSIC/`, etc.) are ignored entirely. +- **SonicStage is dead.** Sony discontinued SonicStage in 2008 (final version CP 4.3). It runs only on 32-bit Windows XP/Vista/7. Modern hosts cannot author OpenMG content without a Windows VM with SonicStage installed. +- **DRM bonded to device.** The CID + challenge-log scheme prevents tracks from being copied between Walkmans. Tracks transferred from a SonicStage library to one NW-A1000 cannot be re-transferred to another even if the library file is shared. +- **Later firmware adds USB Mass Storage mode.** NW-A1000 firmware v2.0+ ("Mass Storage Mode" toggle in settings) lets the user drop plain MP3 into a separate `Music/` directory — but the on-device UI is degraded to folder browsing only (no library / artist / album browse), and ATRAC OpenMG content from SonicStage stops being indexed. It's an either-or. +- **HDD is power-sensitive.** USB unplug during a database rebuild can corrupt the OpenMG tree. SonicStage's repair flow is the only path back to a healthy state. +- **No `iSerialNumber`** in USB descriptor. Per-unit identification must use the FAT32 volume UUID (assigned at format time) or per-track CID; the device itself doesn't surface a unique USB serial. + +## Research Notes + +- **OpenMG DB chunk format.** The `.DAT` files use a uniform 4-byte ASCII magic + length-prefixed chunks. Captured magic bytes confirm: GTLT, GTIF, GPIF, CNIF, GTCL. Chunks (SYSB, GTLB, GTFB, GPFB, CNFB, BFCL) carry length headers + payloads. Metadata payloads are ID3v2 frames encoded in UTF-16LE with the standard ID3v2 frame format (`TIT2 size 02 00 `). Reverse-engineering the database fully is plausibly a 1–2 week project for someone motivated; FFmpeg's libavformat already parses the EA3 container half of the equation, just not the surrounding OpenMG library files. +- **OpenMG DB version word.** Bytes 4–7 of each chunked DAT file carry a 32-bit-LE version. Observed values: + - NW-A1000: `01 01 00 00` (v1.1) + - NW-A3000: `02 00 00 00` (v2.0) + Different NW-A HDD models ship different database format versions despite identical-looking USB descriptor (`bcdDevice = 0x0100` on both). A future writer implementation must handle both versions — chunk layouts within the SYSB/GTLB/GTFB/etc. payloads may differ. +- **EKB (Encrypted Key Block) files.** NW-A3000 has `0001001D.DAT` (EKB v29) and `00010021.DAT` (EKB v33) at the OpenMG root; NW-A1000 has neither. Magic `EKB ` (with trailing space). Filename hex = EKB version number. These carry encrypted OpenMG DRM key material — without the matching EKB version, DRM-bound OMA content from a different device/era cannot be decrypted. Multiple EKBs coexist on a device that has had content from multiple SonicStage versions. +- **SRCIDLST.DAT** (NW-A3000, absent on A1000): 32 KiB pre-allocated "Source ID List" tracking content provenance (SonicStage rip vs Sony CONNECT store vs direct import). Backed up as `SRCIDLST.BAK`. +- **ARDETECT.DAT / C2DETECT.DAT format** (`A_WM/`): magic `MCKF` with `MCKB` chunks. Likely device-authentication challenge files used in SonicStage's device-handshake. ARDETECT seen only on A3000; C2DETECT on both. +- **30GRCT/** (A3000 only, empty on this unit): directory name suggests "30 group recent / count" — likely a per-genre or per-group recent-play tracker. Not seen on A1000. +- **EA3 / OMA container.** `.OMA` files start with `ea3 03 00 00` (literal ASCII "ea3" + version 3). The EA3 header is followed by ID3v2 frames (UTF-16LE, including OpenMG-specific TXXX entries `OMG_TPE1S`, `OMG_TRACK`, `OMG_TYER`, etc.), then the ATRAC3plus audio payload. FFmpeg can decode the audio with `-f oma` once the EA3 header is parsed. +- **Mass-Storage-Mode firmware.** Whether the user's NW-A1000 captured for this profile is on the v1.00 firmware (SonicStage-only) or a later v2.x (MSM-capable) needs verification. The `DeviceInfo`-style files we see on NWZ-E380 do not exist here — the firmware version is exposed only via the bcdDevice USB descriptor (`bcdDevice = 256 / 0x0100` ⇒ v1.00) and via SonicStage's "About this device" panel. +- **PID sharing.** `0x026a` is firsthand-verified for NW-A1000. NW-A1200 (20 GB) and other A-series HDD units in 2005–2007 are believed to share this PID, but not verified. +- **DSEE Engine.** Same as the NWZ family — playback-time DSP, not a content capability. + +## Implementation Notes + +**podkit support is impractical on stock firmware.** Adding NW-A1000 to the mass-storage preset framework would expose the device as detected but writes would silently fail because no podkit code path emits OpenMG-encoded OMA + database updates. + +Realistic paths forward (in order of effort): + +1. **Detect-and-reject.** Add `0x054c:0x026a` to the unsupported-PID table with a friendly message: *"Sony NW-A1000 requires SonicStage (Windows only). Switch the device to USB Mass Storage Mode in its Settings menu for limited folder-browser sync."* Smallest delivery; preserves user trust by failing loudly with cause. +2. **MSM-Mode preset.** If the user reports their device is in Mass Storage Mode (firmware v2.0+), add a `sony-walkman-msm` preset that treats the device as a generic FAT32 DAP writing MP3 into a `Music/` folder. Detection: presence of MSM mode UI marker — exact marker is unknown and would need to be identified on a firmware-v2.0+ device. This avoids the OpenMG database entirely. +3. **OpenMG writer.** Full SonicStage replacement. Out of scope. + +When implementing option 1 or 2: + +- USB hints entry: `0x054c:0x026a → 'sony-nw-a-hdd'` (in `packages/devices-mass-storage/src/usb-hints.ts`). +- For option 1, surface via the same unsupported-PID mechanism used in `packages/devices-ipod/src/tables/unsupported.ts` — extend it to non-iPod vendors or create a parallel `unsupported-mass-storage.ts`. +- Preserve the OpenMG database files.

Differences: + +- **`20PXX/` JPG album-artwork folders** present on disk (written by SonicStage). The on-device firmware is monochrome and ignores them — they exist for SonicStage's PC-side browser. NW-A abandoned this scheme entirely. +- **MACLIST0.DAT** + **MACLIST0.BAK** at OMGAUDIO root carry encrypted per-track Message Authentication Codes for DRM integrity. Each 32 KiB pre-alloc. High-entropy content (no plaintext magic). Required for DRM-bound playback. +- **Different tree/group numbering**: `01TREE` files use hex `0A`–`0F` ids that NW-A skips, suggesting an earlier numbering convention. NW-HD also keeps `.BAK` versions of several tree files; NW-A does not. +- **No `A_WM/`**, no `CONNECT/`, no `30GRCT/`, no `MEDIAGO/` — these were introduced with the NW-A series. + +The implementation constraints are identical to NW-A: SonicStage authoring required, modern hosts cannot easily write the database, plain MP3 dropped onto the filesystem is not indexed. + +## Quirks & Limitations + +- **Same SonicStage dependency** as NW-A. SonicStage discontinued 2008; runs only on 32-bit Windows. +- **No "Mass Storage Mode" firmware variant** that we are aware of for NW-HD5. Unlike later NW-A1000 v2.0+, the NW-HD5 does not offer a drag-drop MP3 fallback. +- **HDD power sensitivity** same as NW-A — yanking USB during a database rebuild can corrupt the OpenMG tree. +- **No USB serial** in the descriptor. +- **MACLIST integrity check.** The `MACLIST0.DAT` file likely contains a cryptographic MAC over each track's CID + key blob. Modifying `.OMA` files without updating MACLIST will cause playback to fail with "Unknown track" or similar. This is an additional gate beyond NW-A's CID/EKB scheme. + +## Research Notes + +- **MACLIST0.DAT format.** Captured 256 bytes show high-entropy content from byte 0 — no plaintext magic. Likely AES-encrypted or signed records, 32 KiB total. Sony's "OpenMG MAC" scheme is described in patents and Sony's white papers; the on-disk layout has not been reverse-engineered publicly. +- **`20PXX/` artwork-ID scheme.** Filename pattern `1G<6-char-id>.JPG` where: + - The 6-character ID after `1G` (e.g. `00C3`) maps to a record in `04CNTINF.DAT` — the canonical track table. + - The suffix `01` / `02` / `P0` indicates artwork variant. `P0` is likely "primary / preview" (small thumbnail for browse). `01` / `02` may be full-size and alternate-size renders. To confirm: dump one JPG and inspect dimensions. +- **NW-HD generation coverage.** Only NW-HD5 is firsthand-verified. NW-HD1 / NW-HD2 / NW-HD3 may use a different USB descriptor (e.g. plain "Network Walkman") and a smaller / monochrome display. PIDs unknown. +- **Tree-numbering scheme difference vs NW-A.** The hex IDs `0A`–`0F` exist on NW-HD but are absent on NW-A. NW-A's IDs `2D`–`37` are absent on NW-HD. Likely a SonicStage-version-dependent set; if a NW-HD is synced with a much later SonicStage, it may gain the higher IDs (or not — fewer browse categories on smaller screens). + +## Implementation Notes + +**Same `detect-and-reject` recommendation as NW-A.** If any podkit support for the NW-HD series is added, it should be the same friendly-rejection path: + +``` +Sony NW-HD series (Network Walkman, 2004–2005) is not supported — +content layer requires SonicStage (Windows-only, discontinued 2008). +The NW-HD generation also requires MACLIST0.DAT integrity records that +cannot be authored from outside SonicStage. +``` + +USB hints entry: `0x054c:0x0233 → 'sony-nw-hd-network-walkman'`. + +If a full OpenMG writer is ever attempted (out of scope), NW-HD will need: +- MACLIST0.DAT generation — requires reversing the MAC scheme. +- Older tree numbering (`0A`–`0F`). + +Note: artwork emission into `20PXX/` is **not** required — the device's monochrome firmware doesn't render the JPGs. SonicStage writes them for its own PC-side UI; an alternative writer can skip them. + +## Inventory + +This profile is firsthand-verified for **one** physical SKU: + +| SKU | USB PID | DB version | Capacity | Captured | Persona ID | +|-----|---------|------------|----------|----------|------------| +| NW-HD5 | `0x0233` | OpenMG 1.1 | 20 GB HDD | 2026-05-13 | `sony-nw-hd5` | + +NW-HD1 / HD2 / HD3 are believed to share the OpenMG content layer but their USB PIDs and any USB-descriptor differences are unknown. diff --git a/devices/sony-walkman-nwz-e380.md b/devices/sony-walkman-nwz-e380.md new file mode 100644 index 00000000..5820a6f2 --- /dev/null +++ b/devices/sony-walkman-nwz-e380.md @@ -0,0 +1,242 @@ +# Sony Walkman NWZ-E380 Series + +Sony's E380 series of entry-level Walkman DAPs (E383 / E384 / E385) covering 4 / 8 / 16 GB SKUs, released 2013.
