Used to be able to get it on sailorvgame.org, but looks like the site is gone.
HOWEVER! I have come bearing gifts! Go here: http://adf . ly/RqyWR or http://adf . ly/SNoQZ (Just remove the spaces)
If neither work, start at the main page here: http://lyzta-games.blogspot.com/2013/07/download-sexy-beach-3-sb3-sailor-moon-mod.html Just use the on page password on bottom.
