Free Items
To enable this cheat, you must first start a game and give heaps of gifts to the same person. Now finish the game you are in and begin a fresh one using your old saved game file and choose the person you gave the gifts. As this person, you should now have all of the gifts you gave previously, for free!

Ending bonus:
Successfully complete the game. When you start a new game, you can immediately advance to the end. Select the "Leave Tomorrow" option at the hotel or pool menu to skip to the ending.

Ending sequence:
Wait for the credits to end to see a extra FMV sequence featuring Zack and the remains of his island.

Bonus music tracks:
You can unlock two hidden music tracks in the game: "How Crazy Are You" (by Meja) and "Is This Love" (by Bob Marley). To obtain them, play through the game once. When you resume that saved game file, these two hidden songs will be available in the Radio Station.

Extra items:
Give a lot of gifts to one character and complete that game. Start a new game on that saved game file and choose to play as the character that received the gifts in the previous game. Those items will be available in your inventory in the new game.

Easy money:
Note: This trick requires Dead Or Alive 3. Play Dead Or Alive 3 and select a character that also appears in Dead Or Alive Xtreme Beach Volleyball in survival mode. The more wins you have in survival mode, the more money you will start with in Dead Or Alive Xtreme Beach Volleyball.

In a volleyball match, the less points the opposing team scores, the more money you will end up getting.

Start the game with any character. The first game of volleyball is the easiest. Make sure you choose "Yes" when Lisa offers to show you around the island. Play the hopping game until you reach the first volleyball match. Play the match, making sure you time your spikes and your blocks perfectly to add extra points. Once you win, wait until the next day at the hotel. Choose "Leave Tomorrow" and start the game again with the same character. Repeat the same steps to get 80,000 to 149,000 credits every time.

Winning a volleyball game 7 to 0 will earn you 150,000 credits. To ensure you never miss, only use the underhand serve as it is guaranteed to go in. This is a great way to earn money quickly, but requires a lot of effort and a good partner.

Use the following trick to win money without winning points. Play as a character that has over one star for her power. While playing volleyball in story mode, have your partner set you up for a spike, wait until the ball is directly above your head, then aim straight for an opponent (preferably the one that is the furthest away). Hit it to the opponent, pressing Attack firmly. If you manage to make then struggle, your partner will award you 1,000 points, and you can usually finish the point off after this spike, or you can reset yourself to perform the spike as many times as desired.

When you do not have a partner, play the hopping game or go to the casino.

Swimsuits in exhibition mode:
Earn or buy swimsuits in story mode (Zack's Island). The swimsuits that you acquire in that mode will also be available in exhibition mode.

Disable commentary:
Enter to the options menu, then change Zack's language to Japanese.

Selecting a partner:
Choose your partners wisely. Try to partner up with girls that have a lot of power; for example, Tina or Hitomi. Then, when you are receiving the ball during game play, try to have them make the first hit upon return, in which case you set them up for a spike using B. Very often, the other players, even if they are blocking, will be knocked down by their enormous spikes.

Moving your partner:
If you do not like the position in which your partner is standing during a match, you can move them by using the Right Analog-stick.

Soundtrack change:
You can change the music playing at anytime by pressing Black (advance to next track) or White (repeat current track).

Force replay:
Hold L immediately after someone scores.

Lock view:
When viewing a "Gravure" movie or another camera-controlled angle, click the Right Analog-stick to lock and unlock the desired angle.

Click the Left Analog-stick to lock the view controlled by it in its current position. Zoom to a desired magnification then press X to lock it at that setting.

Good serve:
In order to receive 1000 points for each serve, make sure that your calibration is adjusted so that it is about 30% (one third of the way from the left of the bar), then press A firmly to throw the ball in the air. Press A firmly again just before the player is about to make contact with the ball. This is very helpful during game play, as you can still get some points even if you lose your match.

Scoring:
When your partner sets you up for a spike, there is an easier way to score. Hold Left Analog-stick Left to make the ball fly closer to the net, so it is harder for the other team to recover. If they try to block your spike, use the same method only use Tap and they will almost never get it.

Toss wisely:
While playing the a volleyball game, it is often useful to toss the ball to your partner who may spike it and score a point. However, if you toss the ball to your partner while she is back half way or more from the net, she may try and spike the ball hard and hit the net, causing the other team to get a point.

Control ball during spike:
Press Left during the spike to spike it short; Right to spike it deep; Up to spike it high (to the top of the screen); or Down to spike it low (to the bottom of the screen). You can do this in a combo (for example, press Down/Right to spike it low and deep.

Preventing cheap shots:
When you are playing a match, and the opposing team spikes the ball so hard that your player receives the ball but hits the ground and the ball flies back over the net, about 90% of the time the opposing team is going to spike that ball at where you are laying. Use the Right Analog-stick to move your partner to the spot where you were standing, so they can bounce it to you while you are getting up, or hit the ball back over the net.
