Naming Convention

Note: This is based on the last official version of the convention, which can be found here and was last updated on 2007-10-30.

Preamble

This convention was created to improve the consistency and quality of all NoIntro Dat releases. To be recognized as an Official No-Intro Dat, it must meet all requirements as described here.

Dats that are not converted will be dropped from the project until they meet the requirements of this convention.

Naming convention

General

General naming rules are described here.

Characters

Only 7 Bit ASCII (Low ASCII) characters are allowed for titles. Accents, Umlauts, High ASCII, Double byte characters are converted to the best comparable Low ASCII characters. Also several characters that are invalid on some file systems are not allowed.

The following Low ASCII characters are allowed:
a-z A-Z 0-9 SPACE $ ! # % ' ( ) + , - . ; = @ [ ] ^ _ { } ~

In addition to the various control characters, the following Low ASCII characters are NOT allowed:
\ / : * ? " < > | `

Discretion is advised for the adoption of special characters in artistic titles (ex. leet speech). In that case they should be converted to their real meaning.

In addition, a filename is not allowed to start or end with a SPACE or DOT character.

Priority

Titles should be primary named after the publisher’s released title (box title). Sometimes the screen title can be more relevant or complete than the box title. In that case the title may be named after the screen title or a mix of the two. If box and screen titles are totally different, the box title is preferred. Common sense is highly advised!

Only one title is used even if the game contains multiple titles or is released with different titles in multiple regions. In that case the priority is in this order: US English title, Europe English title, Japanese title and rest.

Capitalization

Generally all common names, adjectives and verbs should be uppercased. Articles and link words should be lowercased except when first word.

Examples: Adventure of the Hero, Riding in a Car, Travel from Earth to the Moon, From Earth..., Into the Darkness...

The official title written by the publisher or developer can be used as a reference including related titles from other media (movie titles). Some titles also have an unusual capitalization on purpose. In that case, capitalization should be left as intended.

Example 1: RoboCop (= Roboter + Cop)
Example 2: Sonic The Hedgehog is all uppercase: "The" is his middle name, not an article.

However titles that are entirely capitalized should be highly avoided except if the title is an acronym!

Ordering

If the first word is a common article then it will be moved to the end of the main title and separated with a comma. This includes non English common articles too.

Example 1: The Legend of Zelda -> Legend of Zelda, The
Example 2: A Man Born in Hell -> Man Born in Hell, A

Subtitles

Subtitles and pretitles are always separated from the main title by a hyphen " - ". Titles that use a different separation style (ex. colon or "~ Subtitle ~") will be converted to a hyphen style.

If the first word of a subtitle is a common article it will NOT be moved to the end.

Example 1: Castlevania II - Belmont's Revenge
Example 2: Double Dragon - The Ultimate Team
Example 3: Legend of Zelda, The - A Link to the Past

Punctuation

Single and multiple dots should always be included as part of the title. In abbreviated words such as "vs", "Dr", "Mr", etc the dot should be included (or not) as it appears on the title.

Trademark Reminders

Trademark reminders such as "Disney’s" are not included in the title usually. They are only included if they are relevant or part of the title (ex. "Disney Sports"). Also generally original artists or authors are not removed from titles (ex. "Mary Shelley’s Dracula, "Archer McLean’s Dropzone).

Japanese Romanization

Japanese characters are transcribed to roman characters according to a ASCII-compatible form of the Hepburn convention.

The following pattern is generally followed:

• When を is used as a particle, it is written o.
• When へ is used as a particle, it is written e.
• Long vowels are Romanized as in Wapuro romaji
• Loan words are spelled in their original language (e.g. "Pocket Monsters" not "Poketto Monsutaa")
• Suffixes (-san, -tachi, -dan) are usually hyphenated unless a common word
• Capitalization rules apply (lowercase for articles and suffixes)

Examples:

• "Looney Tunes - Bugs Bunny to Yukai na Nakama-tachi"
• "Ninku Dai-2-dan - Ninku Sensou Hen"
