Extra Time
On the beginner track there is a slot machine on the top of the stone arch. To play the slot machine, press Start to stop the movement of the wheels. If you get a 777 you'll gain extra time.
Fast Start
In the transmission selection screen hold the "Start" button down, you will notice that it says "Real Players Only". Keep holding the "Start" button down, until the transmission selection time runs out (You have to choose manual.) From my knowledge this only works on the beginner track. Continue holding the start button down through the whole first lap. If you notice you reach 210 mph just before the Jackpot machine. This will give you at least 2 car lengths lead over other racers that don't do the cheat (if you do it right and don't bump any other cars). This will give you time to get away from the rest of the field and keep on truckin'.
No Computer Opponents
Hold the start button at the transmission select screen. The words REAL RACERS ONLY will appear across the screen. All of the racers must hold down the START button until they choose the desired transmission for the code to work. When the race starts you will notice that there are no computer racers. If you are playing by yourself pushing the start button will enable you to race in a time trial mode.
Play Slots
At the beginner stage, when you see the overhead slot machine, press start to play it while driving.
Beginner Course Tip
When you drive near the Slot Machine, press:
START 3 times
If you get three 7's you'll get 7 seconds of extra time. If you get three Bars you'll get 5 seconds of time.
Expert Course Tips
If you stop on the last corner the seagulls will get closer to your car.
If you drive the second lap in reverse the Statue will be standing on it's hands.
If you stop completely near the statue you can make it spin by pressing the Start button repeatedly.
When the game starts press the start button repeatedly to make the seagulls get larger.

Intermediate Course Tip
If you drive onto the elevated path just before the Pit Road, a billboard will appear stating that you just lost your sponsor.
On the beginner circuit, you will pass under a sign that has different symbols rotating on it. (Like a bingo machine) If you press the start button to stop these symbols, and you get 3 of a kind, you get one free credit. e.g.. You press the Start Button 3 times and they all land on a lemon.
When you are asked to chose manual or automatic gears hold down the start key and choose one. You will be the only car on the track. This only works in single player mode!
ROCKET START : For Expert and Advanced courses only. While at the starting grid, keep the brake pressed, step on the gas and hold it around 6500-7000 rpms. When the race starts, let go off the brake and floor it. You should quickly jump ahead to the front of the pack !
When going into turn 3,slam it into 3rd gear and hook it left, when going strait, put it back into 4th
When you are at the last lap,go by pit work and you are far ahead of the others
On the advanced track slow down when you get to the beginning of the pits and do a U-turn up the ramp and drive into the tunnel, you will waste a credit but it's good for a laugh.
On the expert track slow down and stop on the corner that has the massive statue of Jeffrey from Virtue Fighter. Make sure you can see him clearly and that you are completely stopped. Now press the start button rapidly to see him rap dance.
If you finish any of the races first, hold down the start button to see the credits.

Before inserting coins, put gearshift in Neutral! When selecting racecourse, shift gearshift 4th to 2nd to 1st to 3rd, and step on the brake. The TEAM SEGA Course should appear.

When the total number of game play exceed 700, GASGANO (most right racer) can be chosen.

When "Expert Course" was cleared 50 times, BEN QUADINATORS (most left racer) can be chosen.

Once those racers are appeared on the select screen, they will not disappear even operator clears its back up memory.

This tip comes to you from one of the top racers in the arcades:
At the start of the boonta classic, use jump to boost speed for good start. Then at the first left turn follow the pod that appears in front of you. After completing the turn, straighten out and use the boost button. At this point keep right to avoid all the traffic. Hug the wall on the right turn. On the first big drop should come out at 2nd position. The pod with big wings will knock into you and give a speed boost, which then allows you to overtake anakin right at the entrance of the canyon! The rest, as the saying goes, is history.

Now, do not do any trick on the "Big Air" jump. (Just skate off the edge)
Just after the entrance to the building, there should be an opening in the fence on the left side. Jump through it, and welcome to the secret course.

You can get the credits of the programmers to come up on the screen by holding down a START button during the demo. When it comes to the standard demo w/ Sarah kicking Kage, the credits will come up. Keep holding the START button to keep the credits com coming, or else they will freeze. Also, you can get Kage to _roll_ while the demos are running. Just spin the player one joystick, and he'll roll either backward or forward, it's up to you. On the beginning of the computer intro, you can get Kage to roll off the mat almost before Sarah even tries to kick him. After you finish a game against the computer, the last round which you lost will then be played during the intro. If you got to Dural, the round where you beat Akira will be shown. What a great way to rub in a loss, especially I f the computer had a real good comeback on you :)
KAGE'S FACE MASK It seems that after about 3,000 plays, the mask on Kage falls off instead of just his headband. You can see his teeth and a scar on his cheek.
USING DUPLICATE COLORS In order to play with both players having the same colors, have one player select a character. The other player should now highlight, but not select, the character to the LEFT of that character. For example, if you both want to play Pai, then the second person should highlight Akira. (If you both want to play Akira, highlight Jacky). Now press Right+All three buttons simultaneously. When play begins, you will both be using Player 1's colors (e.g.. both Pai's will have blue uniforms.)
PLAYING AS DURAL It is possible to play as Dural, although the timing to do so is a bit tricky. First, you must beat the computer Dural and have 2 games worth of credits in the machine ready to go. After beating the game, have one player press start and pick a character . As soon as that character finishes smiling, but before the game actually starts, player 2 should press start to interrupt the process. If your timing is perfect, and the stars are perfectly aligned, and you've been a good boy or girl, player 2 may com e in as Dural. Should you be fortunate enough to get to play as Dural, here are Dural's (known) special moves: Wolf's Suplex (Def+Punch), Wolf's Clothesline (For,For+Punch), Jeffry's Body Press Throw (Back+Punch), Kage's Rolling Kick (For,For+All), Kage's Knee Pounce (U p+Punch), Akira's Kick (For,For+Kick), Pai's DDT (For, Down+Punch)
