Even after fixing the game files and using Alcohol 52% with A.C.I.D Wizard, you might get the Securom Error. It would look something like this
If you observe properly, you would see that the drive ( in this case G:) which it gives that error for is your physical ROM ( the actual connected ROM). So if this is the case, then the solution is very simple.
Follow the instructions carefully now. 1. Install the game
2.Extra the Crack folder and Copy and Paste the 'Binaries' folder inside the game folder. Replace the files when asked.
3. Install Alcohol 52% and install everything which is asked in the installation. ( do no install the Alcohol Toolbar ) Also install the SPTD drivers ( x64 for 64bit OS and x86 for 32bit OS )
4. Mount the mini image to the Virtual drive created by Alcohol 52% and go to Virtual Drive options and set the Region as 'Not set'
5. Run the A.C.I.D. Wizard which got installed with Alcohol 52%
6. Now go Inside the 'Binaries > Win32' Folder of the game and delete two files. 'paul.dll' and 'lang.ini'
7. Now go to Binaries > Win32 and run the BmLauncher.exe
8. Wait for 3-4 minutes and the game should start.

At a press conference held by Bruce Wayne to declare his opposition to Arkham City, Wayne is arrested by Hugo Strange's Tyger mercenaries and is himself imprisoned in Arkham City. Strange discloses his knowledge of Wayne's dual identity as Batman before releasing him into the criminal populace. While Strange prepares for the commencement of Protocol 10, Wayne obtains his crime-fighting equipment via airdrop by Alfred Pennyworth, allowing Wayne to become Batman. As Batman, he is first forced to save Catwoman from being executed by Two-Face who hopes to gain respect with her murder. After an assassination attempt on Catwoman by the Joker, Batman tracks the Clown Prince of Crime to his hideout in the Sionis Steelworks, believing he may know the truth behind Protocol 10.
Batman learns from Joker's doctor that the unstable properties of the Titan formula are mutating in Joker's blood, gradually eating away at his body and killing him. The Joker captures Batman and performs a blood transfusion on him; infecting him with the same fatal disease. Batman is forced to find a cure for himself and Joker, or they will both perish. Batman is informed that Mr. Freeze had been developing a cure but has since been kidnapped by the Penguin.
Batman pursues Penguin to his headquarters in the Cyrus Pinkney National History Institute: defeating his forces, his imprisoned monster Solomon Grundy, and ultimately the Penguin himself, before liberating Freeze. Freeze tells Batman that he has already developed the cure but that its instability renders it useless. Batman deduces that the restorative properties within the blood of Ra's al Ghul can complete the cure. Batman stalks one of Ra's assassins to his lair in Wonder City, leading Batman into a confrontation with Ra's and his daughter Talia — Batman's former lover. With Ra's blood, Freeze is able to develop a vial of working cure, but it is stolen by Harley Quinn before Batman can use it.
Batman returns to the Joker and finds him to be fully healed. While Batman and Joker fight, Protocol 10 is activated — A scheme to wipe out the entire population of Arkham City, destroying the criminal element of Gotham. The Tyger troops begin mass executions of prisoners, and Strange launches missile strikes from his base in Wonder Tower. A missile hits the steelworks, burying Batman under rubble. Before Joker can take advantage of the situation, Talia arrives and offers him immortality in exchange for sparing Batman's life. After he escapes with the help of Catwoman, Batman is convinced to put an end to Protocol 10 before pursuing Talia and Joker.
