NullDC_Win32_Release-NoTrace.exe -config ImageReader efaultImage='\' I did a similar thread for EPSXE in that section of the forum, and i haven't decided if i wanted to look at another emulator. The information available on the internet doesn't even work with nullDC 104 r50, but I managed to get all the commandline options working along with function batch files for the program. This will also be very helpful for some of you troubleshooting a specific problem. I will also give all the commandline switches for nullDC the latest version nullDC 104 r50. All from the commandline using a batch file. This will teach you to immediately open nullDC and load a IMAGE at the same time.
