is it possible to put mod in it like Google say?

the game is really great, and it's impressive how close you were able to get it on the PSP! but there are some definite flaws, the arrows arent exactly lined up to the music, and it's pretty sensitive, half a second off and it takes it as a miss, and I can't exactly remember if it did but when I was playing I don't think I lost any score when I got something wrong. and at the moment there is only the tutorial week on easy. and after completing the tutorial week, it says there is more coming soon, and I will definitely download that!
