First, I want to confirm that Cyberia 2: Resurrection works fine on Dosbox 0.72. I have finished the game relatively recently on my Windows Vista Ultimate 32 bit SP1 system.
Hehe, I have to admit I experienced other in-game problems, related to ehmmmm game mechanics and other problems that made the game much worse than its predecessor... 😉
But going back to the technical side of the matter, the game works beautifully on Dosbox 0.72. I can offer more assistance to get the game working for you too, but I will kindly ask you to provide additional details regarding your system and the software that you are running.
To begin with, setting the memory to 64 Mb is not required, 16 Mb works fine.
You should also try making images of your original Cyberia 2 discs and then mounting them using the imgmount, and later swap with the ctrl-f4 combo when you are required to do so.
It will be also very helpful that you post the dosbox.conf that you are trying to run the game with.
Hope that helps. Good luck. 😀
