The game, \"Kidou Toushu Sanshin-Oh,\" had been lost after his PC broke during development. A friend had kept the demo data, but it would not run on modern systems. Kaiware gave the demo binary and data to Codex GPT5.5 and asked it to make the game work on Windows 11. The AI succeeded, though Kaiware notes slowdowns, freezes, and low-quality MIDI playback. The revived version also added a windowed mode, which the original lacked.
