This feature was (I believe) reborn as "-unevenstretch/-nounevenstretch" which first appeared in SDLMAME, later making the jump back to MAME. (-unevenstretch being MAME's default)
... Or maybe it was removed again: http://www.mameworld.info/ubbthreads/showflat.php?Cat=&Board=mamechat&Number=317248
I forget. Either way, a Windows build of SDLMAME will definitely have it.
