I don't understand Turkish, but I understood the video.
You need to have at least 1 cash already. Go to your laptop in The Ville and start the 5 minute job. then go to Charles, breakpoints on, back to laptop - click to speed up the job, pay the 1 cash to speed it up. Charles pops up - edit request, AMF, params, changes, and find the amount integer (-1) - change this to the amount of cash that you want to have.
Execute, execute, breakpoints off, refresh game in browser, and hopefully you will be filthy rich.
Thanks for sharing.
