PlayFusion

PlayFusion is a controller-friendly gaming and media operating system based on Kazeta and Kazeta+.

It keeps Kazeta's insert-media-and-play model while adding an internal game library, automatic loose-ROM media, movies and music, a digital jukebox, profiles, storage expansion, firmware management, additional emulator runtimes, and a fully reworked television-friendly interface.

Download

Download the current public installer from the PlayFusion releases page. The installer is distributed as numbered parts because the complete raw disk image is larger than GitHub's per-asset limit. Download every part and use the included Windows or Linux rebuild script before flashing the IMG.

Before installing, review the changelog and current known issues.

Building

The image builder targets Arch Linux and expects the Kazeta/Kazeta+ build environment. Runtime .kzr files are staged outside Git:

sudo env \
  RUNTIME_BUNDLE_DIR=/absolute/path/to/release-runtimes \
  ./build-image.sh

The public build deliberately excludes private firmware. For a personal build using legally dumped firmware, follow docs/private-build.md and keep the private staging directory outside Git.

Firmware and copyrighted content

Do not submit console BIOS dumps, encryption keys, commercial ROMs/disc images, private signing keys, user profiles, or save data. PlayFusion includes a BIOS Manager so owners can import legally obtained files after installation.
