The new FAQ needs Extra Stage and OMES requirements for each style (AC and CS, IMO).

I don't even know 7th CS's off hand. I don't think BMUS has one, and that's kinda notable.

Any of the above, if performed on your final stage, will let you pick a fourth song as your "extra stage."

What the topic creator was referring to, though, is the song-specific special extra stages that allow you to play the hidden Extra Stage song before the machine is fully unlocked. That is, playing Genocide on a non-unlocked RED machine, Scream Squad on a non-unlocked Happy Sky machine, etc. Those requirements vary by style, but here's a brief rundown:

* 7th (MAX 300): AAA a flashing 7* with HARD for your third stage.
* 8th (Sakura): AAA a flashing 7* on ANOTHER with HARD for your third stage.
* 9th (PARANOIA survivor MAX): AAA a flashing 7* on ANOTHER with HARD for your third stage.
* 10th (1st Samurai): AAA an 8* on ANOTHER with HARD for your third stage.
* RED (GENOCIDE): AA three songs on ANOTHER with HARD for your 1st, 2nd, and 3rd stages. Your 3rd stage song must be a 7* or higher.
* HAPPY SKY (Scream Squad): Same as RED, except that your three songs must be of increasing difficulty and the final song must be at least a 10*. You also cannot use Random.

This, of course, is AC info....
