I had a paper list i completed but have no idea where it's at. I started or added to a thread on the subject and a year or more ago if you want to check. I'm almost positive I had 1/2 the sounds down at that point. I did explosions and hits.
EDIT: Found it
http://bbs.hitechcreations.com/smf/index.php/topic,245096.0.htmlI went to the training area and found a few guys to help me with this. i asked one guy to jump in a spit 16 (50's and 20's) and another in a spit 9 (30's and 20's) and another in a K4 which once hits sounds like a 20 i think.
You can do your own tests but if you want to fool around with different sounds Film it. Every time you switch the sound replay the film and the sound will change. You can check all sounds this way if you like. Puffy, gear, engine, tire, train ect ect.
RANGER just came out with a new sound pack that i downloaded just to hear it. IT IS VERY GOOD!! It also included a nice PW sound.
You can mix and match many sounds from different sound packs into the game depending on what you like..
