Gain new stuff quickly:
After playing through 15 holes of the last course in World mode, make sure
to save it. You must be winning, of course. Then after you have finished in
first place and waited through the credits and recieved your new ball, club
and player. Simply reload the save game and play the last three holes (still
staying in first place) and get an all new ball club and player.
Unlocking clubs, balls, and characters:
All the clubs and balls can be unlocked by successfully completing the world tour
on difficulty level one (in options). You can also unlock only three of the characters
in the level. For each increase in level, you have the ability to unlock two more
characters. (i.e. by successfully completing world tour with the difficulty set
at level four, you can unlock a total of nine characters.
