After some headaches I finally got Batman Arkham Asylum ( non-GoTY ) to work on Steam. I had the game years ago. For some retarded reason Valve removed the CD key for the game in the properties. And to insult it has a securom validation server that no longer works. I had to get a pirated launcher and dll file and another dll file to bypass all the securom checks and then use a CD key from Street Fighter 4 to activate the game because it used Gen 1 GFWL DRM and not the later SSA keys.

I did get a kick out of the modded .dll file being named whysosrs.dll though
