I'm curious if the Mega Trainer 1.1 works for the Steam copy of Batman: Arkham Asylum. I couldn't find a way to make it work, so it probably doesn't, but just wanted to make sure.
That would be really great!
The trainer I'm referring to does indeed work for the Steam version. You need to launch the trainer first and then launch the game.
When the game gets to the main menu, press F1 and it will say "Trainer Activated". Should work from then on.
