Anyone play these two games on the Wii?

I need some tips for "Super Samurai" Boss stage on DDRHP1. it's just impossible to beat O.o
I've turned off the gimmicks, freeze arrows and motes, but it's still plenty hard.
Would appreciate all tips I could get for DDR.

===================
6A. SUPER SAMURAI =
===================

UNLOCK: Beat Battle on EV Venue

Artist: jun
Genre: Speed Rave
BPM: 170

Difficulty:
BEG: 2
BAS: 6
DIF: 8
EXP: 10

Play Notes: There are several stops throughout this tune. The first three
occur in the opening "build-up" section. There are a few more over the
course of the song, including one that's almost miniscule.

Expert Notes: As you'd expect from a venerable ten-footer, lots of long
streams with crossovers, sixteenths thrown in liberally, and jumps and
freezes all over the place. Watch out for the latter half, where long
clusters of sixteenths plague the chart.


Hopefully this helps, I took it from the GameFAQs guide which you can view here : http://www.gamefaqs.com/console/wii/file/938140/50448

Trying and trying, just too hard ^.^
Practicing with difficult on free play mode now. Most difficult songs are easier than Super Samurai on Baisc

I hope I'll be able to beat it within a few weeks ^.^
