Star player/handicaps
Note: Win the Star Cup with a character (get three
cups in a tournament). Hold [R] while selecting that same
character to make him have handicaps and make him more powerful.
A yellow star will appear in the bottom right of the screen (for
player one) or bottom left of the screen (for player two). Press
[L] + [R] to have a left-handed player that is also
a star character. Being a star player will enable you to serve
stronger and play better. If you make Bowser a star player he
will be able to serve up to 136 mph. Note: Donkey Kong Jr. and
Shy Guy are already star players when they are unlocked.
Slow shot
Press [B], then [A].
Control the ball
This trick can be done with any player, against any
player. Hold [Analog-stick Left] or [Analog-stick Right]
as you hit the ball. This will send it in whichever direction
you pushed the stick.
Shy Guy
Win the Star Cup/Singles Tournament. This character
can already use the handicap cheat after being unlocked. You do
not have to win the Star Cup as this character.
Donkey Kong Jr.
Win the Star Cup/Doubles Tournament as any character.
This character can already use the handicap cheat after being
unlocked. You do not have to win the Star Cup as this character.
Yoshi and Baby Mario court
Win the Mushroom Cup/Singles Tournament as Yoshi.
Mario Brothers court 2
Win all the Doubles Tournament Cups as Mario. Note:
This is another Mario Brothers Court, but not the alternate way
to get the previous one.
Super Mario and Wario Courts
Win the Mario mini-games for Mario and Wario in the
Game Boy Color version of the game. Then, refresh data and send
it to the Nintendo 64 through a Transfer Pak.
Wario Brothers court
Go through all the cups for Double Tournament with
Wario.
Waluigi Court
Win the Medallion Match and set a new high score in
challenge mode in the Game Boy Color version of the game. Then,
refresh data and send it to the Nintendo 64 through a Transfer
Pak.
Birdo/Yoshi court
Complete the Star Cup Doubles as Birdo to unlock the
Birdo/Yoshi court.
Special Cups
Go through all the Tournament Cups with all the characters
(including Shy Guy and Donkey Kong Jr.) to unlock the Special
Cups, which are much harder than the previous one. Press [R]
while selecting a character to access the Special Tournament in
the menu.
The three Special Cups in order are Rainbow Cup, Moonlight Cup,
and Planet Cup. Once you win a cup, you will move onto the next
one.
See the same replay again
Press [B] while in a replay and you will see the
replay again. This can be done at any point of the replay for
as many times as desired.
Shining eyes during replay
If you are playing against Waluigi and he makes it
past you, during the replay his eyes will shine for awhile.
Better chance of winning
When playing against the CPU, if you win a game or
a set (in the final of the cup), save the game, then start again.
In case you lose, you can continue the game and start with the
advantage.
When playing against the CPU, press [B] then [A] for
a slow shot close to the net, then run up to the net. After your
opponent hits it, quickly hit the ball away from him. The ball
will zoom by him, leaving him no time to react, and giving you
an extra point.
When playing a two player tournament against the CPU, note that
when one CPU player goes to one side the other goes to the opposite
side, so as not to leave a single open space. Their main formation
will look like this:
X
X
-------------------------------
Try to get in the front row. Then, go in front of the opponent
closest to the net. If the opponents happens to change rows, stay
in front of the person closest to the net. Leave a little space
between you and the net. Then, when the ball is headed toward
you, save up as much power as possible then hit the ball over
the opponent that is closest to the net, and right in front of
you. If done correctly, the ball will go over one opponent's head
and his or her partner will either be too far away to hit it in
time or barely hit the ball.
