Tetorica Playground — For AI

Use these type definitions and working examples when generating JavaScript for the Tetorica browser Playground.

Type definitions

• Common Playground API
• YM2612 / Mega Drive selection
• YM2608 / PC-98 selection
• YM2203 / PC-98 selection
• YM2610 / Neo Geo selection

Read the common API and the one chip-selection file that matches the target Playground.

Working examples

The canonical example source is playground_examples.js. The following links load representative examples into the Playground. Loading an example does not run it automatically.

• Open these source files from Playground FILES → examples to run them.
• Live Loop — tempo, notes, and named loops
• Ambient Choir Sample — sample loading, FX, and live state
• Noise Ocean — generated noise and parameter control
• FM API Beep — direct YM2612 setup
• PSG Scale — SN76489-compatible tone API
• Parallel FX — branched effect routing

Execution contract

• Generate JavaScript, not TypeScript.
• Top-level await is supported.
• Playground APIs are available as globals and through pg.
• Use stable, unique names for independent liveLoop() and livePrepare() state.
• Project files are read with file(); relative paths resolve from the running file.
• Network APIs and external package installation are unavailable during user-code execution.

Suggested prompt context
