Sakura has unused damage sprites in her tiles, based on her sweep damage animation from Street Fighter Alpha 2 and onward. These graphics also went unused in Super Medal Fighters, but they were later re-used in Super Gem Fighter Mini Mix for when Sakura slips over and falls, although her face was slightly re-drawn for that game.
This unused Score Ranking icon for Birdie appears in this game's tilesets, but its palette isn't present or correct. It's a leftover from Street Fighter Alpha 2, where it was used.
Like Super Street Fighter II Turbo, Super Puzzle Fighter II Turbo is known as Super Puzzle Fighter II X in Japan. The Announcer's voice clip was also changed to reflect the game's changed name.
In the Japanese, European, Asian, and Hispanic versions, there is a Mode Select menu which lets you battle against the CPU or with a friend. The US version removes this.

Also, in the Level Select menu, some extra Japanese kanji on the difficulty icons were removed in the International version.
To better correspond with the game's logo, the shape in the logo on the game's HUD is a X in the Japanese version and a star in the international versions.
Hsien-Ko and Akuma are named Lei-Lei and Gouki in the Japanese version, which is consistent with prior appearances of both characters. The Announcer's voice clips were also changed to reflect this.
To do:
Add the Japanese-exclusive character-specific Win Quotes here and translate them.
In the Japanese version of the game, all characters have 11 additional Win Quotes, as opposed to the International version's 4 per character, which will be different depending on their opponent whom had lost the match to it. They were not translated for the International version, which makes them all go unused.
