Where do games disclose AI use?

This game is made by a single dev, and sold for a fair price. In order to do that this dev needed the help of AI. So some pre-rendered assets in this game were created with the help of generative AI tools, always under my direction and with every asset reviewed by me the developer: certain illustrations, backdrops, and UI art; some music tracks and sound effects; and character voice lines generated via text-to-speech from scripts written by me the developer. The game design, the gameplay, physics, and large parts of the code are entirely human-made, and no AI content is generated at runtime.

AI has been used to help develop the game's cover art.

What parts AI applied to are: pictures like icon, button, background; language translation. And no more other visual elements like, objects rendering, model, post process effect have used AI.

Occasional use for marketing materials and promotional images.
