1. you need CheatEngine. 2. select process--in this case Faerie Cloud Racers 3. scan type=exact value type=double 4. Lose then scan 1 5. Lose another time then scan 2 6. you should have 3-4 addresses, copy the 2 address(s) with no decimal point. 7. change both its value to either: a)-100 or b) 4 DONT FREEZE! voila! invincible! P.S After every round the value gets reset to 0. So all you have to do is just repeat step 7. +rep if it helped!
You might also want to remind people that you have to be using flash 7 to search double byte values... If anyone is using flash 9, see my guide in my sig!
