[QUOTE="Luca91, post: 10359423, member: 504031"] Hey K, thanks for the interest in this. The goal is to avoid patching the game executable and trick it to think that the disc in inserted. Many games released on cdrom also loads game files directly from the disc, so I implemented a file-redirection mechanism to redirect file access on the fly (from the hardcoded path to a custom path defined by the user in the configuration file). This is not "drive emulator", you don't have to keep the ISO file on your computer at all. As you can image, this will not work for specialized DRMs (such SecuROM, Safedisc, Laserlock etc) as these protections rely on the disc (real or virtual) to read data used to decrypt the executable in memory and so on. That said, in these cases, it is still possible to unwrap the DRM and then use DCE to emulate the disc checks (or disc accesses to load data). Theorically it would be possible to emulate specialized DRMs without even a "drive emulator" (at least for older versions of Safedisc, SecuROM etc) but it requires in-deep knowledge o each version of that DRM and also obtaining and specifying the decryption key for each game (this can be read from the game). This is something interesting and I might check it out in the future. It is a lot harder and time consuming than simply removing old DRMs with x64dbg+Scylla (as I demonstrated in my technical papers) or creating an automatic unpacker/unwrapper (for example the semi-automatic SecuROM 2.9-4.68 remover script for x64dbg that I've released some time ago [URL='https://github.com/x64dbg/Scripts/blob/master/SecuROM_2.9-4.68_Semi-Automatic_Remover.txt']HERE[/URL]). If you have more questions, feel free to ask! :) [/QUOTE]
