We need those entries scraped. [Contributing](https://github.com/gbdev/database/blob/master/CONTRIBUTING.md)

Read CONTRIBUTING.md first, then inspect existing Game Boy and Game Boy Color entries to learn the database format. Review the linked gbsilk, Sizuku, and To Heart sources and determine the required metadata; done means adding the requested entries consistently with the existing database.
