Good question! Unfortunately I’ve got no idea.

If anyone knows the song that starts playing at 6:55 in this video please let us know!

Edit: Looks like it might be custom written for the actual CR Virtua Fighter, the pachislot machine. Here’s the full song.

Edit 2: The song title is Kokoro no Chikara.

Edit 3: If you’ve got a NicoNico account here’s a video with great sound quality!
