i have a gq-4x( willem) burner. i need to combine a 128k rom and a 256k rom into a 512k image. the command line is:

copy /b CPU_5B.128 + CPU_5B.128 + CPU_5C.256 CPU_5C.512

how do i do that with the rom burning software?

You really need to provide more context here. At the risk of
stating the obvious that is an MS-DOS/Windows command line command
to combine two copies of the first ROM followed by the second into
a single image - presumably the ROM images are in binary format
and the secnd copy of the first is being used as a spacer to pad
the second ROM to the correct starting offset. You'd execute that
in a Windows command line window (Windows key+R, type "cmd" and
press enter, cd to the folder containing the files and enter that
command) With that done you have a single 512k ROM image to burn
as one file with your device programmer and and software.

It's not clear at what step of the process you have issues so you
really need to be more specific.
