have you tried youtube i know they have sound files for all mvc 3 and other fighting games. Maybe try there. Or get ps2 emulator and rips the sounds shouldnt be too hard if they have a soundtest menu
I already found street fighter x tekken but I want the original tekken sound effects tried ripping them but I could not extract the large munge file and if I rip them in game some throws have other sound effects mixed in like the enemy grunts and slams.
I think that just dumps raw files, which require a lot of effort to get to anything usable.
If you want Tekken 6 sounds, I suggest get the PSP iso and use PSound on it.
