then make all the dll, exe and bios files read only. error level 104, right? well try replacing every single dll that nulldc says does not work or cant find. or what would be great is one exe and maybe another file to save configuration and game saves (that would be two files instead of one).i do have three emulators for my nintendo ds that are just an nds file and my roms and thats it no bios and crap. i wish the emulators work out of the box, you know? no setup or replacing files. It worked to replace the stuff with me whn i got psxfin emulator. maybe also apply read only attribute to your roms if you use roms. then you right click all the dll and exe and the bios files and make them read only. What you should do is to replace the files that it sais it cant read ir that are missing. this happened to me on nulldc and also other emulators. Would really appreciate some help on this.

I've looked at other posts on this topic but its not helped me at all. I have tried EVERYTHING to get it working but it's not happening.

When I transfered it to my downstairs system, which has the exact same motherboard, graphics card, memory, ram, cpu - I get this message: I have NullDC working perfectly on my upstairs system.
