diskOS Disco! 1.0.3

The album cover is the interface. diskOS Disco! 1.0.3 is a touch interface for the FiiO Snowsky Disc's round
screen, built on b0hemia's diskOS 1.2.4.

Testing release, as-is, no liability. Flashing rewrites the Disc's root filesystem. Back up your music and
keep the saved stock image safe. Not affiliated with FiiO, Snowsky or Ingenic.

Flash it (first install)

You need a Disc on FiiO firmware V2.57, the official V2.57 firmware ZIP, a Linux computer and a good USB cable.

1. Download Source code (tar.gz) below and unpack it (or git clone https://github.com/zmd22/diskos-disco).
2. Optional, but recommended: make your own update keys, so you can install later versions from the SD card.

   sh ui/tools/owner-keys/diskos-keys.sh
   cp diskos-keys/diskos-root.pub.pem payload/

3. Flash:

   ./install.sh                     # first time only: host setup
   ./diskos-installer install \
     --firmware SNOWSKY_DISC_update_20260909_v257.zip \
     --variant public \
     --ui payload/mq_ui \
     --ota-key payload/diskos-root.pub.pem      # leave this line out if you skipped step 2

   Power the Disc off, hold Volume Down and plug in USB. With a key, check that the ota: ON … key sha256 line
   matches sha256sum payload/diskos-root.pub.pem before you answer y.

Update an existing install from the SD card

Download mq_ui, then sign it with your keys and copy the folder to the card:

sh ui/tools/owner-keys/diskos-sign.sh mq_ui 1.0.3      # -> ./diskos-update/

On the Disc: Settings › System › Update from SD Card › Update, then restart. It runs as a trial and rolls back
by itself if it doesn't start. More: docs/UPDATING.md.

What's new in 1.0.3

• Ogg Opus (.opus/.oga) files are now indexed and played, with their tags and lengths - ported from diskOS PR #19
  by ingvarr777.
• AirPlay and Bluetooth streaming switch on again from Working mode.

Also in 1.0.2

Fixes the "Player didn't respond" message that still appeared a few seconds after start-up: a background request to the
player (switching off its own idle power-off) now waits for the player quietly. And flashing now always runs the build
you flashed: older builds kept from SD-card updates no longer take over after a flash.

Also in 1.0.1

A CD look for Immersive (Disco Options > Immersive: Vinyl or CD), a tidier Working mode ("Playback", spinning
arrows while switching), and a stability fix: no more "Player didn't respond" at start-up, and starting a song or a list no longer sometimes fails.
Commands to the player now wait for it while it's busy (starting up, rebuilding a playlist) instead of being dropped.
Details in the changelog.

What's in 1.0 (unchanged)

• Disco theme (default): the cover fills the screen, a navigation circle slides out of the right edge, Music with
  a rainbow progress line or a progress arc around the rim, the title menu (Favourite, Album, Artist, Queue, Lyrics,
  Immersive), Disco Options, and Disco versions of Quick Settings, Equalizer, Volume, Standby, Weather, Search,
  Queue, Battery and more.
