How do you reverse a cheat or is it even possible

[Road Rash]

I bought the Game Shark greatest hits a while back and used the infinitte cash cheat so I could avoid having to go into Special Conditions and race the night away in order to buy a car to race in an event only to have to need a different car for the next event. Basically it was just a time saver now its nightmare. I wouldn't mind like 10 or 20 mil in the bank so I could by a acr when needed or wanted but then that way it would be worth it to get prize " money" for races as well. now I just exit out after a race to avoid waiting for cash to rack up. I figured why not buy a butt load of pescasolas (60) then selling them after reversing the cheat I wouldhave a cool 58mil, but NOOOOOOOOOOOOO! The cheat don't reverse! Oh well, If I'm stuck with it so be it, but if there is way to reverse it can someone tell me? I already tried loading the Shark disc and starting it without the cheat on but that didn't work

You can't reverse the cheats in that sense but you could always enter a code that gives you 10 million credits, for example.
Give me the cash cheat you've got and I'll try to make a 20 mil one for you

mY FIRST REPLY TO THIS SEEMS TO HAVE VANISHED INTO CYBER SPACE! Darn capslock...but, I'm not sure how to send you the code, first my PS2 isn't online and second I really don't know howto if I could, the code is on the disc. If you told me how to send it I probably could.

You mean the codes exist only on the disc and are not editable?
I've only got an Action replay which stores the codes on memory card so you can view, edit or delete them freely

Anyway, if you can enter your own codes try these, one of them should give you about 16.2 million credits
