Need help with extension mvec [Playfirst Playground SDK]

[PsyXo]

Hi guys!

There are files with the file extension mvec, rather it is the font, made on the game engine, Playfirst Playground SDK, but the developer has long ceased support of the development of the engine under windows and servers for download are closed in Google, found only under Macos, I have a question, can anyone have this engine, can share, or maybe there is a script for unpacking and packing the file/fonts with the extension mvec.

I would be grateful for any help for unpacking this file.
