Many fan-translated visual novels, dramas, or game patches use internal naming conventions like [code]_[character name]_[timestamp]_[version]_[quality] . Example: adn591 could be a project ID, miu shiramine the character name, 020013 a release time (02:00:13), min for minimal edition, and extra quality for enhanced assets.
