You said in your first post, "Please, would be nice to add both the addition of 999,999$ and the infinite money.", which the max money code that's in the main cheat file both sets your money to 980,000-ish, and also stops the count from decreasing. And yes, in order to make the money able to decrease, in its current form, you need to restart.
Your latest post doesn't answer anything, I'm trying to understand what it is that you're asking for. I understand exactly how the code works, so I don't know why you're just stating how they operate.
