I'm currently using the file at https://dagobah.net/flash/Bloons_TD.swf after some googling.

Is this the correct version of the game? Does flashpoint provide the swf file as well and can someone share it with me? :)

You can find the swf flashpoint uses by going to the flashpoint folder and going to \Legacy\htdocs\ninjakiwifiles.com\Games\gameswfs and the swf is called bloonstd_moved.swf hoped this helped!
