Hidden Bosses can be used once they have been defeated. The conditions of the Bosses to appear are to fulfill two out of the following three conditions. If you play with a Capcom groove you will get God Rugal, and if you play with a SNK groove you will get Shin Gouki.
Defeat the Middle Boss (Geese or Bison/Vega).
Achieve at least one Finest KO.
The Custom Groove option appears once a normal Boss has been defeated (normal Gouki or Rugal). Normal Bosses appear by fulfilling two of the four following conditions.
Achieve four or more special KOs.
Middle Boss has appeared.
Achieve two or more LV3 super combo KOs.
Press Start at the Groove selection screen.
Boss challenge mode becomes available under the following two conditions. Both hidden Bosses (God Rugal, Shin Gouki) must already be defeated and unlocked. Hold X + Y while selecting arcade mode.
Highlighter any fighter at the character selection screen and press a button. Allow time to run out and the game will start in one on three tag team mode. Note: Do not select one on one battle mode.
Clear Boss challenge mode with no continues. The "Extra Option" becomes available in the game.
Press Start while editing the colors for your character to display more options on the left side of the screen.
Defeat all characters straight in survival mode. The custom groove option settings will become infinite.
The middle Boss appears when the following conditions are all fulfilled:
The CPU has not made over six "first attacks".
The CPU has not made three or more Special KOs.
Hold Start + FP after winning a stage to make your character say an opponent specific quote. Hold Start + FK to make the character talk with a team member.
After unlocking the EX Options, go to the "Extra Option" and set "Life Gauge" to "No Damage" and "Groove Gauge" to "Infinity". You will be able to blast through all 46 characters in no time.
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.
Once everything is unlocked, set your Super Bar to "Infinite" in extra options mode. Select Rock in any mode and choose the P Groove (Custom Combo Groove). When you fight, press HP + HK for Custom Combo, trap your opponent in the corner, and do the Rising Tackle. When your move is being executed hold Down. When you touch the ground, press Up + HP to execute another Rising Tackle. Repeat this until you get a 99 hit combo or your opponent loses. Note: This can also be done with Terry.
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.
