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!
