Street Fighter Zero 3, known as Street Fighter Alpha 3 in US regions, has a downloadable Sony PocketStation mini game counterpart.
By playing a series of quick-burst mini games, fighters can be leveled up and pushed back into the console game. Sadly, this feature was removed from the American release (but can be accessed using a cheat device).
Here is a quick 90-second review of this game you never played.
Special thanks goes to Patreon supporter ANAPAN for supplying me with this PocketStation and the USB PS3 Mem Card adapter. This video would not have been possible without his support.
