when i play with a texture effect example : FitLink.pac I not hear the sounds...
Which effect is it (As in, what was it called when you doownloaded Ex. Z-Saber)? The answer to this problem is that yoou have a different region of Brawl for the effect.
Azz...I have the pap versoion, but why the fitmotion work ? (NTSC)
There's your answer.
You have PAL. The effect is NTSC. Only way you can have sound if if you burn it on an .iso.
Or asking the one who made that effect to make it with a PAL version of it (like everyone asked me to do with my blue Falcon Punch). But that would depend on the person that made the texture.
You know, in theory you could just extract the effect .pac file out of FitLink (NTSC) and replace it in the FitLink (PAL) while still leaving all the sound info. Could you upload the effect .pac you are using and a fresh pal .pac?
EDIT: Also upload the FitMotionEtc file of the other effect you want and a fresh pal FitMotionEtc (of the same character).
