Its no longer working..... They made rules now that if money is alot in start then they will show message like "Update game". So may be need diff mod like unlimited free purchase for real money.
@JokerArt : I can confirm this, i just tested it. Since there is no "unlimited boosters" added, you have to buy them with your unlimited money. But, as soon as you bought a booster, the game gives you a "forced update", which means, you are banned.
