As mentioned on the welcome page, I don't believe there is a way to play the latest version of CTGP-R without a disc. Pretty sure the creators are against piracy or just don't want to go through that route of developing. There's v.1.02 that can be played without a disc, but I don't think you can go online. Unless one can convince the creators to create an ISO or patch of some sorts for backups, there's nothing you can do.
