I bought the 100yen music one. It's in the game options menu. In one of the menus, you'll see a choice with "BGM" in it. You can listen to all 14 song tracks.

I bought the Ball Type, but I have no idea what it is. I assumed it was to choose different balls, but I can't find where to choose, if that is the case.

For the people who have unlocked a lot, go ahead and list what you bought, and where it is located.

Thanks in advance

I found where to access the 3 different balls. Fevernova, Tricolor, and another one. It's in the second page of the match options (where u select length, weather, etc).

The ball thing that you dont know is random. it is an option for the cpu to choose which match ball is used.

oic...so only two balls to choose from...that's unfortunate. Hopefully, with the patches, come new balls..like the champion's league starred adidas, and the Nike Geo's.
