As interesting side note: Tracks 18 and 19 (競技中(NO.1), 競技中(NO.2)) give credit to Shiro Hamaguchi as composer and arranger. Both tracks can be already found on the
Pocket Monsters Anime Sound Collection as track 08 and 21 (ポケモン!ゲットだぜ!, 大混戦) on which Shinji Miyazaki is credited for both, composing and arrangement.
