48-in-1 boards aren't a MAME ripoff (at least not like the 1000-in-1's that use an actual PC). They come with all DIPS set to "off". Horseboy IS THE MAN. I found all settings save for one at Twin Galaxies and the majority of `em are factory default!
Here is the list...for anyone who does a search in the future:
