Capcom Generation 5 was released in 1998, and includes the first three versions of the Street Fighter II series: The World Warrior, Champion Edition and Hyper Fighting. This collection was unfortunately not released for the Saturn outside of Japan.
This version of Hyper Fighting is much like the original arcade game, with the only difference being load times between each fight. The SEGA Saturn version's load times are faster than the Playstation version, making this the superior 32 bit version of the game.
This version has a couple of extra features, such as a training mode, a gallery and a mode which lets you pick different versions of each character and fight each other -such as Hyper Fighting Guile against World Warrior Ken. This concept would be expanded upon greatly in Hyper Street Fighter II. If you've got a Japanese Saturn, this collection is worth seeking out.
