Linux-native mod manager for Neverness to Everness.

---

One desktop app (Tauri + React + Rust) for the whole NTE modding workflow — PAK loader, 3DMigoto, video and texture swaps, the in-game piano, and screenshots — designed to work the way Linux already does. No Wine, no PowerShell scripts.

Features

• Home — launch NTE via Steam or directly via protontricks; active profile always visible. (Non-Steam installs are supported too — file management works, you just start the game yourself.)
• PAK Mods — import .pak / .zip / .7z / .rar archives, enable per-profile, browse GameBanana inline, auto-check for updates.
• 3DMigoto — install the loader and individual mods, toggle scripts.
• Videos — replace Cinema, TV, and advert clips with custom MP4s; a companion audio sidecar watches the game's Custom/ dir and plays the matching MP3 in sync.
• Textures — swap in-game images (posters, billboards, paintings, gacha banners, loading screens) with one click.
• Piano — three modes:
  • MIDI file: play a .mid on the in-game 36-key piano via simulated keystrokes.
  • Live device: forward a real MIDI piano into the game in real time.
  • Transcribe: convert an audio file — or a YouTube URL via yt-dlp — into a playable .mid using the PianoTranscription model.
• Screenshots — thumbnail grid browser for the game's screenshot folder.
• Profiles — multiple mod loadouts, switchable in one click.

Requirements

• Linux (developed on Fedora/Nobara; tested on KDE and GNOME)
• Neverness to Everness — via Steam Proton (recommended), or any install if you pick "I don't use Steam" in the setup wizard (no in-app launching then)
• 7z on PATH for .7z mod extraction; ffmpeg/ffprobe for the Videos view; protontricks only for Steam launching. Missing optional tools degrade gracefully with a clear message.
• Python 3, mido, evdev — Piano tab core
  • Live mode also needs python3-rtmidi
  • Transcribe needs librosa torch piano_transcription_inference
  • URL transcribe needs yt-dlp + ffmpeg on PATH
• Write access to /dev/uinput for the Piano tab. The Piano tab detects this and offers a one-click fix (via pkexec); equivalently, do it yourself:

  sudo usermod -aG input $USER && newgrp input
  # if that's not enough on your distro, add a udev rule:
  echo 'KERNEL=="uinput", GROUP="input", MODE="0660", TAG+="uaccess"' \
    | sudo tee /etc/udev/rules.d/99-uinput.rules
  sudo udevadm control --reload-rules && sudo udevadm trigger
