3D Movie Maker is copyright Microsoft, 1995 or 1996 abouts. Make a backup of your 3DMOVIE.EXE/v3dmm.exe files!
This site doesn't actually upload and download your file. It's all done in-browser, so there's no slow file transfer and no copyright infringement.
So far this has only been tested on the US 3DMOVIE.EXE, If I can locate any other languages I'll add support for them too.
This site has been tested in Chrome 27-37 and Firefox 22. Other browsers may work if they're not named "Internet Explorer".
