I should have sent the camera shot.
Only 91k Hong Kong Euro 9-line, which was pretty good for a almost-laggy Pop'n Music 11 machine.
To get it what I mean... Here is my non-accplished video of HK Euro with like a 85k. And start to lag at some parts.
YOUTUBE: HK Euro 9-line with lag~
That is it and will not get good scores for a long time. :\
