Batman: Arkham Asylum DVD9 to 2xDVD5

[fetobanana]

I followed peterf instructions and had the same error (\Disk4 folder) so I searched the web and found another conversion that worked for me (WinXP64)

DVD9 -> 2xDVD5

1) Create 2 folders: \BATMAN1 & \BATMAN2.
2) Copy to BATMAN1 all files/folders EXCEPT data4.cab and data5.cab.
3) Copy to BATMAN2 all files/folders EXCEPT data2.cab and data3.cab.
4) Delete gfwlivesetup.exe from \BATMAN1.
5) Edit autorun.inf from \BATMAN2 with:

[autorun]
open=0
icon=autorun.exe,0

6) Make ISOs or Burn with BATMAN1 and BATMAN2.
7) Instalation sequence is DVD1, DVD2, DVD1.

Note: Installation doesn't ask for DVD1 after DVD2 it gives a "Wrong Disk" error, when this happens insert DVD1 and click Retry to finish installation.
