Unlockable 4th difficulty, "gekimuzu".
To obtain a 4th difficulty, you need to get the highscore on
all 4 modes of gameplay.
Zoo keeper: 1200000+ points needed.
Tokoton 100: 1800000+ points needed.
Quest mode: 10000+ Yen needed.
Time attack: 600000+ points needed.
After getting all 4 high scores, a 4th difficulty appears in the top line of the option menu.
This difficulty means "Expert" or literally "difficult-player" and has a huge advantage of doubling all the normal points you achieve. This secret was found by mtpfreak and verified by bemani.
Hitting the 'ILLUSION' bonus will score you ‘1500000’ points.
Basically if you're ultra skilful and with a bit of luck this is possible to do. First you have to get 3 blinking tiles on the screen; next you must connect all three in a row, horizontal or vertical. After it's been connected, the screen will flash with a spark bursting out and the word 'ILLUSION - 1500000' in the centre of the screen.
Note: This Bonus is also in GameBoy Advance Zooo.
