How really can someone make a private server of a flash game?

I understand that its complicated but I would like to learn the way. So you download the swf file with inspect and then what?

Thank you

You'll need at least an emulator to run the Flashgame, or the source code. You cannot just "download the swf" and upload it at 127.0.0.1, I mean you can but it's not gonna work.

SWF-Editing needs mostly decompiling the swf-file itself and edit it with adobe e.g.

If it's multiplayer, you'll need database/server/configs etc.
