Reproduction refers to the re-production or renovation of works made in the past on the same medium.

the word "remake" was first used to mean remake movies, and later it was widely used in TV series, TV animation, video games, music, fashion and books (out of print). Among them, the reproduction of video games and out-of-print books is also called "replica" (only works containing replica elements in remake's works).

First of all, the screen ratio of the official so-called remastered version is different from the first version, from 4:3 to 16:9, because the animation trend in recent years is like this.
