EyeToy - Groove - PlayStation 1
Master level difficulty:
------------------------
To unlock as master difficulty, get an A in one of the tracks.
You will then have a new difficulty level. It is (as far as
I can tell) exactly like hard mode but with less warning when
the heads will appear
Track 21-25:
------------
Complete tracks 1-20 all the way through on any mode
