yeah, MAME emulates that mapper (assuming you mean the same mapper as the Flashback Mini 7800), but we don't have the ROM, and I can't find the ROM anywhere to add it. Had we had the ROM it might have been emulated sooner than 15+ years ;-)
in other words, if you can make sure somebody on the MAME team / here has access to it, that would be handy, as it needs adding.
