Question about sound file changes, gear ratios, and quilling whistles in PS3

This all depends on the boards and the code used.  PS-2 boards require special flash code loaded at MTH to do specific functions.  Like QW and Pantograph operation.  IF you do not have the flash board loading the sound file won't matter.  That is why you can't fix your GG-1 with operating pantographs with an upgrade kit board.  It is only coded for steam/diesel/electric/trolley and articulate steam.  None of the special functions.

PS-3 is different in you have the ability to load the flash program yourself.  But you stuck with the speed curve of the file you load.  So if the file thinks the engine has a ratio of 20 to 1 with 2 in drivers, but it really is geared differently with different driver size scale speed is off.  Chuff is semi inconsequential since you can adjust that separately, but you have no control of speed tables.

Where they are located is inconsequential also.  The flash gets them from where they get them.

Yes you can load a PS-3 premier sound file into a PS-3 RK engine and gain QW.  You don't need the flash file that is already imbedded.  At least for PS-32 code.

Try it, you can always reverse it as long as your original file is listed on the web.  G
