Tiger Woods PGA Tour 2004:
Decide where your ball goes:
Ok, when you take a swing and rapidly press the '3' button to get maximum power on the backswing. This works the same way, but instead of more power, this tip will give you control of the speed and direction the ball rolls (and bounces) after its flight through the air. What you have to do is after taking a swing and the camera switches to the top view so you can watch the ball soar through the air for 300 or so yards, quickly decide where you want your ball to roll and press the direction on the direction pad (you can change the course as much as you want until the ball hits the ground).
With the direction being pressed, tap the '3' key. You will see a golf ball in the bottom right of the screen with an arrow circling it in the direction you are pressing. The more rapidly you press the '3' key, the faster the arrow will spin and the more your ball will roll. I discovered this when I was just playing around with some buttons while waiting for my ball to land and take my next shot.
Never Play a Bad Hole:
When you're in a tournament and you haven't done so well, press pause and quit the game before you put the ball down, and you can resume play in that tournament and start that hole all over again. You can do this as many times as you want until you're happy with your performance on that hole.

Big Score in Burnside:
At Burnside, you start off the level in a half pipe. While in that half pipe, you might find a little bug that will permit you to get a big score. It's simple, just do a slide while in the half-pipe, and when you reach a small space between the net and the half-pipe, your player will "enter" the half-pipe. Now you can do tricks and more tricks, racking up a big score. Then, when you go out without falling down, the judge will give you a 99!
Better Scoring With Greater Air:
The first one is a "Switch Benihana + Front foot impossible." Do this by pressing the south east direction (all the time while doing the trick) then buttons 6 and then 4. This gets you a score of 4,000 the first time, then 3,000 the second time, then 2,000 on the third time, and 1,000 points the fourth time.
The second trick is a "720 Madonna + kickflip to Indy." To do, this press the north west direction (throughout) then a successive press of the 6-Key and the 4-Key. If done right and over a channel/narrow gap you should get some great points: The first time you should get 10,000 points, the second time you'll get 8,000, the third time you'll get 7,000, and the fourth time 6,000, and so on. Every subsequent time you do the trick, you will get one thousand less points.
The third trick is a "540 Stalefish + Switch Channel Gap + varial" This is done by holding the south west direction constantly and successively pressing 6 and 4 one after the other. You'll get 8,000 the first time you do this, 6,000 the second time, and then 1,000 points less each subsequent time.
The fourth and final one is called "Rocket air + Fingerflip." You do this trick by hitting north east direction constantly as well as the 6-Key and the 4-Key one after another. Gets you: 1st time is 4500+ and then decreases by 1000 points every time you do it.
SonicN:
Unlock Moon Zone:
Beat the game with all 7 Chaos emerald's and play Sonic's X-Zone. After you defeat him, you will unlock the moon zone.
Fly high:
Play as Sonic (recommended), Miles, or Knuckles. Go to Zone 1 Act 1 and go to the area where the first loop is located. Stand on the sliver of land, then charge a Spin Dash for twenty seconds. Dash to the right and hold Down/Right. You will go down the hill (not getting all the rings). Eventually, you will go so fast that you will leave the screen. Sometimes it does not launch you off the cliff at the end.
