the development team. In house producers usually have greater access to the original game and to the original artists and authors. Whom can be consulted about changing art assets and story concerns. Since Japanese companies prefer the post-gold method, in-house translation is favored. In-house productions usually have lesser mistake and an overall smoother localization. The downside is that this causes a delay between the releases of the international and home version. Another means of localization is through the unauthorized effort of fans. Fans of video games without an international release may be willing to put unpaid effort into localizing a game if the game is not released internationally. The most notable example of this is the Mother 3 (2006) localization. Fans attempted a petition to Nintendo to localize the game into English, when this failed they undertook the process themselves.

Music may also vary according to
