.

Achieve over 1500 GPS by the end of the game.
Defeat the Middle Boss (Geese or Bison/Vega).
Achieve at least one Finest KO.

To unlock Shin Akuma or Ultimate Rugal, defeat whoever shows up as the final Boss. Choosing the Groove system and whatever character goes with the Groove system is not needed. For example, defeating Ultimate Rugal with Shin Akuma equipped with the N-groove in the final stage will unlock him.

Travis Mills.

Extra options:
Clear Boss challenge mode with no continues. The "Extra Option" becomes available in the game.

Use the following trick to easily clear Boss challenge mode and unlock the "Extra Option" mode. When both Shin Akuma and Demon Rugal are unlocked, go to the main menu and enter the arcade mode while holding Triangle + Square. While still holding the buttons, select EX1 or EX2 Groove and Maki (the girl). Then, when you start, never attack. Instead wait for your opponent's attack and hit him with Maki's counter move. Use a hard kick on the left of the controller. Note: Before starting, go to the normal option, select the easiest difficulty setting and increase the damage level.

Hint: Akuba: Special combo:
To do one of the special combo moves, quickly press Square(2), Toward, X, R1. Note: You must have the C groove on with the default setting.

Hint: Kim: Extra attack:
Unlock the "Extra options" and change the Groove Gauge to "Infinite". Choose Kim as one of your fighters. When in battle, use his Phoenix Kick super move. When you hit the opponent, he or she cannot maintain themselves in the air after the hit. At the correct moment, you can hit them again with the same attack. If timed correctly, you can do a 3-hit combo/knockout with Kim's Phoenix Kick.

Hint: Kyosuke: Extra hit:
Execute any groove level Double Shadow Cut Kick (Down/Forward, Down/Forward, then LK, MK, or HK). HK or FK is recommended. As soon as Kyosuke executes his wave, do another Shadow Cut Kick (Down/Forward followed by LK, MK, or HK) and it will count as an extra hit. This move can also be executed in Rival Schools as where it was originally shown.

Hint: Mai: Chun-Li like appearance:
First, choose either Mai or Chin-Li. Then, choose the opposite character. Mai will now look like Chun-Li.
CHHOUN66.

Hint: Yun: Extra attack:
You can add an extra attack to his 3-hit super upper punch attack. When you use the move, after you launch your opponent in the air with the upper punch, wait for about half a second and execute his push and stomp attack. You will immediately launch your opponent to the other side of the screen, and the attack calculator on the side will mark it as a 4-hit combo.

Hint: Getting a Finest KO:
Beat up your opponent until his/her life is low enough to finish them off with a special KO. Stand near your opponent and wait for them to taunt you. Then, do the special move and you will get a finest KO. You also have to either beat the mini-Boss, or receive 1500 GPS before you finish the final round in Osaka to get to God Rugal.

Hint: Unlocking Shin Akuma and Ultimate Rugal easily:
Use the character shown on the groove selection screen (in arcade mode) on the left. For example, Ryu for C-groove, Terry for N-groove, etc. The other character(s) can be anyone desired. Doing this takes you to Ultimate Rugal if you picked one of the Capcom grooves and characters, and to Shin Akuma if you picked a SNK groove and character.
Toby Innocent.

Hint: Easy Boss challenge mode:
Choose a good fighter such as Ken or Ryu. When you are facing the last Boss, if you are losing by one round and there is not a lot of power remaining, press Start on controller two and repeat until you win.
Ricky Lee.

Use Haomaru the samurai. He looks weak and slow, but his slash and jump slash has a wide range and also does big damage. If you jump around with Airguard equipped and slash at the correct time, you will not have a problem defeating any Boss.

Hint: Easy survival mode:
After unlocking the Extra Options, go to "Option Mode" at the main menu. Go to "Extra Options", select "Player One Life Gauge Type" and change it to "No Damage". Then, go to "Groove Gauge Type" and change it to "Infinite". After this, start survival mode and defeat all 46 characters without taking damage and your Groove Bar will always be full.

There is an easy way to win when playing in "All Survival" mode. Go to the options menu and set the difficulty to the minimum. Next, set the damage level to maximum. Exit the menu and select the "All Survival" mode. Choose the S Groove and continue to the character selection screen. Then, choose Zangief. Keep getting your opponent in the corner and grab him/her endlessly. Notice that this move does more damage than before. The best damaging move is the Russian Aerial Spin when done at its highest level. Your enemy should go down quickly. It is possible to complete the game in seventeen minutes by doing this. Note: You will fight Shin Akuma and Ultimate Rugal at the end. After accomplishing this, you will unlock the infinite edit Groove points.

Hint: Infinite combo:
If you have Ex 1 or Ex 2 groove with infinite groove points, you can create a endless chain of level 2 super combos. If Ex 1 or Ex 2 groove is like the C groove, you can use almost any level 2 super combo if you have unlimited super combo gauge. If you start with a level 2 super combo, you can keep hitting your opponent until you want to stop. You just have to keep hitting the buttons for the super combo. You can finish by doing any level 3 super combo. This works well for Ken's Shoryu Reppa or just about any level 2 super combo, then finish with a level three or one combo. This is useful for eliminating Bosses such as Ultimate Rugal or Shin Akuma.

Hint: Easy points:
Set the levels on the easiest level and increase the damage. Fight the first person. He or she is very easy. Do good damage and make sure you end the first round with the Super Combo. Play the second round. Beat them up, then press Start on controller two to enter a versus fight. The points you have accumulated just before the second player joins will be the same when you return to fight the first person again. You will also have to defeat them twice. You can keep repeating this process until you have accumulated the desired amount of points.

Successfully complete all survivor mode, with any EX set if needed. Attempt to create an EX groove greater than 4000 points. Answer "Yes" and the game will allow you to do so.

If you want to unlock something, select SNK characters with a SNK Groove (for God Rugal) and Capcom characters with a Capcom Groove (for Shin Akuma). Keep fighting until you get to an easy to defeat opponent. As soon as you defeat them, press Start on controller two and choose someone. Defeat them, then you can restart the "easy win" fight in arcade mode. Keep doing this until you have 1500 GPS to fight Shin Akuma or God Rugal.

Hint: Goro Damien cameo:
Have a match featuring Kyo vs. Bermiriu (fighter who puts his hair straight up) at the Shanghai stage to see a special cameo by Goro Damien. He will be sitting in the background of the rotating platform watching the fight, making gestures every time someone gets hit.

Hint: Street Fighter 3 reference:
In any mode, go to the stage in England. At the far right edge of the screen, you can see Dudley in the background reading a newspaper. Dudley was a British boxer from the Street Fighter 3 games.

Hint: Cameo appearances:
Look closely at the edge of the ring in the Shanghai stage to see June from Star Gladiator, an early Capcom fighting game. In the England stage, aside from Dudley, you can see Elena from Street Fighter 3 at the left side of the level, and Billy from Fatal Fury in front of the building marked "C.V.S.". During the second part of that stage (the night area that usually appears during the second round of the fight), you can see Rose from Street Fighter Alpha and Rouge from Power Stone having a conversation in the same location where you saw Elena at the start of the first round. In the Nairobi stage, look on top of the car on the left side of the stage. You will see Falcon from Power Stone watching the race.

In the African stage (the dunebuggy stage) there is a cameo appearance by Falcon from Powerstone (man in red) and Leona Heidern from King Of Fighters (girl in green). They are both on top of a jeep on the left side of the stage.

Glitch: Move difference:
Unlock Shin Akuma and go to versus mode. Choose Akuma vs. Shin Akuma and do each of their Shungokusatsu moves. Shin Akuma's is a 33-hit and Akuma's is a 15-hit move.
