I have an .iso image for the game. This requires a relevant programme to 'run' it. I use Daemon Tools Lite. On Daemon Tools, I just use the Quick Mount option. I don't know about the rest of it. Once it is mounted, it behaves as a separate physical CD/DVD/BRD drive, but it is virtual, so it will use the next available drive letter on your OS. Would anyone (mods/admins, mostly) want me to upload the .iso image to either here (if I can, and of course with permission (it is 512 MB (536,987,648 bytes) in size)), or perhaps PM a mod and give them a link for them to make it available on here? (Unless an .iso image exists within the shareable files here already.) I also have the Metropolis Dawn expansion pack and the Helicopter Patch, as well, but I expect these two are available already.
Before I do this (if I get the go-ahead), I intend to upload the .iso image to an online virus-scanning site, and sharing the results here. I am thinking of VirusTotal, which uses "70 antivirus scanners and URL/domain blocklisting services, in addition to a myriad of tools to extract signals from the studied content".
Of course, if an .iso image is available already, or I do not receive permission to do this, then nevermind.
