First, I uninstalled all of JJ2 series, and reinstalled.
and.. follow the suggestion..





Jazz2s(-).exe is old one, and Jazz2.exe is plus.



I tried the way that stijn and Treylina's saying.

the file size is only 21MB.
Well ok..

Let's play it..





Wow.. is the plus version support the beautiful colors like that?
Oh, and also, background is skipped. cool.
(colors are seems just reversaled, but it just screenshot. I never changed the setting.)

Oh, the music?

I'm just hear the only one sound : Beeeeeeeeeeeeee...eeeep - I never hear that horrible sounds in my life..



This screenshot is run with s3m files. musics are perfectly supported, and colors are very fine.
So, It's not a system's problem.

Well anyway.. 'wav'file is failed. Perfectly.
then.. Let's play with mp3..



Oh shit.. not again!..
WHY!

Is the 'Basical' problem may caused by am I Korean? or what?
I think that.. JCF members are just kidding me even admin..
I'M NOT FUNNY YOUR JOKE LIKE THIS! NEVER!

OK. NO MORE ATTEMPT. I'LL NEVER TRY AGAIN!!
EEEEEVVVVVEEEEERRRRR!
