Hello Alien Firefox,
After having the same problem and tried out several diffrent money trainers for Scarface 1.00.02 (none of them did work) i created my own money trainer.
It aint giving you a amount of cash but it will give you for sure unlimited Cash.
So when you use this trainer your cash wont decrease anymore.
hope this will help you out.
Greetings,
Citera
