How to organize parsing of html5 and flash games?

Question

Parsing

Hello everyone, I'm looking for a way to automatically parse html and flash games.
Tried different parsers, but they fail to pair all used game files. All files are visible in the "Network" tab of the browser console, they are loaded via GET and POST requests and are called by js or swf files of the game. You can download them manually, but most often there are dozens of such files, and sometimes hundreds. Pictures, sounds, videos. Competitors somehow know how to completely download everything, maybe someone knows a program or a way to download html and flash games automatically?
Examples:
html
m.igroutka.net/ru/001/igra-vzlom-bankomata/
i.igrutut.ru/sm/stikmen-pobeg-iz-tyurmy-3/
m.igroutka.net/ya/pianino/igra-piano /game.html
flash
mariogames.be/Transformers_Games_Portal_Of_Destruction_Game
