No. CPS1 games have custom hardware in the C-boards. You can't just rom swap the games if you have a CPS1 boardset. SF2CE is way more common and thus less valuable on the street than GnG. So someone made this hack so people could convert the boards. You could probably double the street value after the conversion, but it's gross and might end up with some dickhole erasing an undumped SF2CE version in the process. They aren't all dumped yet.
Also it's completely worthless from an emulation/gamer's perspective.
