Each time you complete arcade mode with a character you unlock their EX (or Extra) form in the secret shop (the "EX" form is the exact same character with new, different, or altered moves). To use a characters "EX" form, you must purchase it from the secret shop. Go to the character selection screen and hold Start while choosing your character to switch from the "Normal" to the "EX" character. While still holding Start, press A, B, X, or Y to select that character.
Each of the special stages is unlocked by defeating the character. The special stages or modes show up in the secret shop.
|Special Stage, Mode or secret||How to Unlock||Cost|
|Gouki's (Akuma) stage (secret 69)||Defeat Akuma in arcade mode/SNK Groove||1,500 vs. points|
|Morrigan's stage (secret 67)||Defeat morrigan in arcade mode||1,200 vs. points|
|Nakoruru's stage (secret 68)||Defeaut Nakoruru in arcade mode||1,200 vs. points|
|Pair match mode (secret 71)||Defeat Morrigan AND Nakoruru in arcade mode||1,800 vs. points|
|Adjustable ratios in vs. mode (secret 72)||Defeat Akuma in arcade mode||1,500 vs. points|
Complete both the Capcom and SNK grooves in arcade mode with "Normal" Ryu and "Normal" Iori. Secrets 34 ("Evil" Ryu) and 49 ("Evil" Iori) will now be available for purchase in the secret shop, and will cost 7,000 vs. points each.
To fight Gouki(Akuma) in arcade and pair match modes, unlock and purchase Gouki's "Shadow" (secret 62) in the secret shop. It will cost 500 vs. points. You must have at least 80,000 GPS (groove points) before the start of the final match to get him to appear.
To fight Morrigan and Nakoruru in arcade and pair match modes, unlock and purchase their "Shadows" in the secret shop. (Morrigan's "Shadow" is secret 63 and Nakoruru's is secret 64). Each of Morrigan and Nakoruru cost 700 vs. points each. To get them to appear, you must not continue and have at least 60,000 GPS (groove points) by the end of the third match (which is the third team you face). To fight Morrigan, choose the Capcom groove. To fight Nakoruru, choose the SNK groove.
Note: The easiest way to fight them is to go to the game options and set the difficulty to the lowest (easiest) setting, time to infinite, damage to the lowest (minimum) setting, and change gauge to max.
There's a secret workaround that lets you earn FREE vs. points for the secret shop. Go to training mode, choose your characters and opponent, then just leave the game on for around 2 to 2.5 hours at the battle screen. You earn points automatically up to 999 vs. points. Though 999 is the maximum number of vs. points that you can earn in one training match, you can exit the training mode, re-enter, and you can do this over and over again to get as many vs. points as you like.f
