This is a Mighty Number 9 Real Time Modifier or Cheat Trainer for the Playstation 3. Made with the PS3Lib dll library and open source!
This is a very simple RTM. I know there are much more complex programs available, but this is using the newest patch and should offer enough features to get you through the campaign. This game is incredibly unstable, so instead of infinite HP, I had to make it auto heal you every so many seconds.
