It ended up arriving perfectly and it makes me happy. Also I found an old camera sheathe in which it fits perfectly and has a belt loop, definitely lucky but amazing combo along my ZSN-HIFI IEMs ^w^

Pulsar: a full pixel-art astronomy/astrophotography overhaul for the Echo Mini's dark theme (theme B / midnight black).

Features:
- M31 boot animation, starry shutdown screen
- Sky-panorama home menu with astro icons
- Star-trail Now Playing and volume screens
- Moon-phase charging and battery icons
- Pulsar and radio-dish USB screens
- Constellation clock, binary-star L/R balance
- Recolored menu/library/settings icons, navy text boxes (firmware patch)

Attached GIFs/images show the Now Playing screen, the Home screen, boot up / shutdown animation, charging animation, and media library.

Install: copy HIFIEC39.IMG to the player root, update the firmware, then select theme B (midnight black) in the settings.

Echo Mini 8GB / Firmware 3.9.0 (HIFIEC39) only. Flash at your own risk.

diskOS 1.2.0 is out. It adds support for the latest official firmware (V2.57), eight themes, more library and playback features, and in-app updates for future releases.

Full write-up with every change and screenshots: https://ko-fi.com/post/diskOS-1-2-0-V2-57-support-eight-themes-and-in-B4H5280Y37

What's new

• V2.57 support. Install over your own unmodified official V2.57 firmware. V2.09, V2.28 and V2.40 still work. On V2.57 you also get screen rotation, volume-key actions, idle power-off, a charging limit, Sleep Timer options and Bluetooth codec selection.
• Eight themes, each in dark or light, plus Outdoor Mode, three text sizes, a language setting and a new startup animation.
• Library and playback: an Up Next queue, song lengths, album views for artists and genres, Song Info, timed lyrics, and more playlist tools (rename, export, delete, M3U import). More formats are indexed, including APE, DSF/DFF, CUE sheets and SACD ISO. Indexing a format doesn't guarantee it plays.
• In-app updates. Future diskOS releases can be installed over Wi-Fi from Settings > System > Update diskOS. Updates are signed and only change the diskOS app. You can turn updates off during install, or stop downloads later in Settings. 1.2.0 itself still needs a full flash.
• Fixes for album art, library rescans (now with progress and a Stop button), Wi-Fi feedback, playback handling, and back swipes that also tapped a button.
• Installer: a macOS package for Apple Silicon, and Linux setup now works on Arch, CachyOS and Fedora.

Known issues

• After a restart, Wi-Fi can take up to about a minute to connect. If it shows no IP, reconnect in Settings > Wi-Fi.
• A "Player didn't respond" message can appear once on the first boot after installing. It's harmless and playback works.

Fixes for both are planned for a future release.

Installing

1.2.0 needs a full flash, including if you're on 1.1.3. You need your own unmodified official FiiO firmware file. Back up your microSD card first.

Other community projects worth a look

• diskOS Ring by u/No_Surprise700: a reworked interface built on diskOS, with an immersive cover and lyrics view, a working enqueue mode, a lyrics and cover auto-tagger, and a circular equalizer. https://www.reddit.com/r/snowsky/comments/1wtzk9r/diskos_ring_beta_is_here/
• Browser control by u/Top-Childhood374: a web app that runs on the Disc, so you can control playback and manage your library from a browser on your home network. Early developer build for now. https://www.reddit.com/r/snowsky/comments/1wtjnhk/your_snowsky_disc_controlled_from_a_browser_would/

Thanks to everyone who tested and reported bugs.

What's next

Development slows down for a while as I focus on other projects. I'll keep building in the background and I'm still around to help with issues.

diskOS is an unsupported beta. Installing it reflashes the device. Recovery is normally possible but not guaranteed, and installing may void your warranty. diskOS is not affiliated with FiiO or Snowsky.
