I am working on a rapid fire cheat for a semi-automatic pistol that fires one round, each time you press the button - regardless if you are holding the button down (i.e. it's not automatic). I have found the rapid fire address and the instruction that writes to the address. It is strange, because, if I nop the instruction, the value does not change, but I do not have rapid fire. However, if I slow the game down, I do have rapid fire...for a moment. The more I slow the game down, the more bullets come out of the gun and vice versa. I know, for a fact, that multiple bullets are not coming out of the gun at the default game speed 1.0.

Also, another strange thing...when I am looking to see which instructions access the address, the game becomes laggy, and I am able to see that the rapid fire value is flashing between ?? and numerical...even though my pointer address is not changing. I thought this might be why the rapid fire is only temporary, however, even when I NOP the instruction that writes the value, the flashing does not occur, but the rapid fire is only temporary.

Does anyone have any idea why this is happening?

Thanks.
