Hi All, Thank you for your replies!!! Helped me get it working. I had tried an INF file, but it was continuedly causing errors when it was building, but i used the example at https://github.com/tianocore/edk2-non-osi/blob/master/Emulator/X86EmulatorDxe/X86EmulatorDxe.inf and it worked a treat.... INF included for anyone else looking for another example of how to get an EFI file loaded automatically, without source code.
