As the title states, I've got the original Defiant of Shrine Maiden DVD-ROM(found it at Otakon last year, bought it on impulse), and I want to know if there's any way I'm able to play the two later versions. Additionally, I've seen that there's a version of DoSM with the subtitle "-Zero-". This is the one I'm most interested in, since it enables some features I don't yet have available, namely Map Actions.
Am I able to get the full version of DoSM using the disc I have and updates? I've looked on Hachikuma's site, and updated to v1.150, which is the farthest I saw that worked. (I tried downloading the first update patch for CoGHB and it failed, so I'm figuring I can't do that probably due to not owning that disc, or at least not until I get to -Zero- if I can do so.)
tl;dr:
-I have the original DoSM disc. Can I get any/all of the following updates?
-Defiant of Shrine Maiden -Zero-
-Counterattack of God Human Being
-One more fight on only One God!! aka Slash Buster
Thanks in advance for any information on this~!
