When using Daemon Tools 4.03, we can mount NRG files and ISO files, right? But here's the thing: When we mount a .NRG file, it doesn't show up in the selected drive. Example, if we mount a game on [H:] and go to Explorer, the name of the game doesn't show up in the H: drive. However, when we mount an ISO file, the name correctly shows up in the corresponding drive and we can access it in explorer. But, in Chankast, when we have the ISO file mounted and we select 'Play' an error says : "Please insert game disc". On the contrary, when we have the .NRG file mounted and we select 'Play', it loads but fades to black and returns to the chankast bios screen. Why is this so? When we have the .NRG file mounted, shouldn't the insert disc error come and when we have the ISO file mounted, the game should work? What kind of file does Chankast_Alpha25 need in order to play that game? (Not asking where to get the file, but simply what kind of file is required. If this thread seems inappropriate, close it if necessary).
