In the GBA version, even though the box cover is shown as Super Puzzle Fighter II, the title screen still shows it as it was originally: Super Puzzle Fighter II Turbo
The game was named the Best Puzzle Game of the Year in PSExtreme Magazine's 1997 Extreme Awards (Vol. 3, Iss. 3).
There is a remixed vocal version of Sakura's theme song available as a prize in Street Puzzle mode. The song is called "I Want You to Know" and (I think) is performed by the seiyuu (voice actor) for Sakura in Street Fighter Zero 2. I believe that in order to open this song, you have to defeat Sakura in SP mode a couple of times first.
