Infinite money sounds great, but if you activate this glitch the Law faction becomes hostile toward you and their aggro range is increased.

There is a similar cheat that you can activate with a cheat code, but your parents need to input the code on the title screen before starting your game. You'll start in "New Game +" with huge bonuses to cash and influence. The Law faction becomes friendly toward you, and the MegaRich are neutral instead of hostile, and they'll even forgive minor grievances sometimes.

I never learned the code so I can't help much more than that. Sorry 😔
