Nozio NO CD patch is only for original version (1.0.0) so I did a little of binary diffing of his patch/a bit of debugging and found where the protection is on version 1.0.4.
The following code makes the cd check:
00004f22 e8e9a80000 calll 0x0000f810 - call the cd check 00004f27 84c0 testb %al,%al 00004f29 7405 je 0x00004f30 - jump if no cd is present
So the patching is very easy, just NOP that jump if equal call and that’s it. Quick & dirty !
Have fun !
