Toolbox Mode connects via REST API for full device control\n- **Live video and audio** — Real-time UDP video and audio streaming with audio balance control\n- **CRT shader effects** — Metal-based post-processing with scanlines, bloom, phosphor afterglow, shadow masks, barrel distortion, and vignette\n- **8 built-in presets** — Clean, Home CRT, P3 Amber, P1 Green, Crisp, Warm Glow, Old TV, Arcade\n- **Custom presets** — Save, modify, and delete your own CRT configurations\n- **Toolbox controls** — Start/stop streams, load SID/PRG/CRT files, reset/reboot/power off, access the Ultimate menu\n- **Keyboard forwarding** — Type on your Mac keyboard and have it appear on the C64, with an on-screen strip for C64-specific keys\n- **Screenshot and video recording** — Capture the CRT-processed output with synchronized audio\n- **Password support** — Connect to password-protected devices\n- **Zero dependencies** — Pure Apple frameworks (Metal, Network, AVFoundation, SwiftUI)\n\n## Requirements\n\n- macOS 14.6 or later\n- Xcode 26 (to build)\n- A Commodore 64 Ultimate device on the local network\n- Toolbox Mode requires firmware 3.11+ with REST API enabled\n\n## Download\n- [Download C64 Ultimate Toolbox for macOS 14.6 and later](https://amiantos.s3.amazonaws.com/c64-ultimate-toolbox-v1.0.zip)\n- Or, [Purchase C64 Ultimate Toolbox on the App Store](https://apps.apple.com/us/app/c64-ultimate-toolbox/id6760209871?mt=12) for automatic updates.\n\n## Building\n\nOpen `C64 Ultimate Toolbox.xcodeproj` in Xcode and build. No package dependencies to resolve.\n\n## Usage\n\n### Viewer Mode\n\n1. Start the VIC Stream and Audio Stream on your C64U, pointed at your Mac's IP address\n2. Launch the app and click **Listen** under Viewer Mode\n3. Click the video to access audio and CRT filter controls\n\n⚠️ For more detailed setup help check this: [Quick Start Guide](https://discuss.bradroot.me/t/c64-ultimate-toolbox-quick-start-guide/80)\n\n### Toolbox Mode\n\n1. Enable **FTP File Service** and **Web Remote Control Service** in your C64U's Network Services menu\n2. Launch the app and enter your C64U's IP address under Toolbox Mode\n3. Click **Connect** — streams start automatically\n4. Click the video to access device controls, file runners, keyboard forwarding, and more\n\n### Keyboard Shortcuts\n\n| Action | Shortcut |\n|---|---|\n| Disconnect | ⌘D |\n| Volume Up/Down | ⌘↑ / ⌘↓ |\n| Mute | ⇧⌘M |\n| Take Screenshot | ⇧⌘S |\n| Start/Stop Recording | ⇧⌘R |\n\n## How It Works\n\nThe app communicates with the C64U over multiple channels:\n\n- **HTTP REST API** — Device info, stream control, file loading, machine control, keyboard injection (Toolbox Mode)\n- **UDP port 11000** — Video stream (4-bit indexed color, converted to RGBA)\n- **UDP port 11001** — Audio stream (16-bit stereo PCM at ~48kHz)\n\nVideo frames are assembled from UDP packets, converted from the C64's 4-bit palette to RGBA, then rendered through a Metal CRT shader pipeline at the window's native resolution.\n\n## Links\n\n- [Quick Start Guide](https://discuss.bradroot.me/t/c64-ultimate-toolbox-quick-start-guide/80)\n- [Devlog](https://discuss.bradroot.me/t/c64u-viewer-c64-ultimate-toolbox-devlog/78)\n- [Support Forum](https://discuss.bradroot.me/tags/c/projects/13/c64-ultimate-toolbox/36)\n\n## License\n\n[Mozilla Public License 2.0](LICENSE)\n","funding_links":[],"categories":["Other"],"sub_categories":["Text"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Famiantos%2Fc64-ultimate-toolbox","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Famiantos%2Fc64-ultimate-toolbox","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Famiantos%2Fc64-ultimate-toolbox/lists"}
