I originally copied the assets folder but v30 does have quite a few visual changes via css etc. Safest method is to just overwrite the pics, pic and mp3 folders. I also have needed to change the code for mc's room at home as v30 uses icons for the laptop and a couple of other items which made the old menu disappear. I have attached that updated start file.i copy the assets 82.5Gb v29 western version from rpdl torrent to the SOB Version 30 and i donwload the StartV30Eng and i Overwriting every thing the game did not work
I am pretty much experimenting and playing v29 assets on the v30 update more out of interest than anything - plus I get to learn more about how the thing is coded etc, so don't treat this as a normal version. V29 Western versions plays fine so the download is not wasted, you just don't get the v30 additions.
