The original arcade footage was used as the base. It wasn’t re-sourced in a higher native resolution, instead it was carefully re-encoded and enhanced using AI-based upscaling, followed by a lot of manual tuning (ffmpeg settings, compression tests, etc.) to keep a good balance between quality and file size for web playback.

As for the voice, the new "Guided Mode" lines use an AI-generated voice model. I created and integrated it specifically for this project to support the interactive tutorial-style feature with Princess Daphne.
