Victory quotes:

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: 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 Ultimate Rugal.

Hint: Easy Boss challenge mode:
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:
Enable the "Infinite health and gauge", then choose Shin Akuma. Hold Right Analog-stick Down and allow the game to idle in this state for twenty minutes. You should have defeated all of the opponents and get 9,999,999 points. Note: You must be using Eo-ism.

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:
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.

Hint: Street Fighter 2 music:
Set up a match with Ryu versus Sagat in training mode. At times music from Street Fighter 2 will play.
