For Final Fantasy X HD Remaster, "Battle Theme" was remastered by Nobuo Uematsu and Tsutomu Narita using real instruments. It received an orchestrated metal arrangement. "I wanted to rearrange the song to have a grander sound while maintaining the mood of the original at the same time," Narita said of the big-band-like upscaling to the "Normal Battle" theme. "Brass and string instruments were already important elements of the original song, so we decided to expand into a full orchestral piece by adding other instruments as well."
An arrangement of "Battle Theme" was composed by Takeharu Ishimoto. It appears as a default theme. The original PlayStation 2 version is also available. Both can be bought from the shop for 3,600 gil.
