Possibly emu version.
I know a full 106 romset will differ but I have happily made use of far older romsets without issue, contrary to others experiences, so you don´t have to be specific, though some games will obviously be lacking from older sets.
Enjoy your Mame on Pandora.
Eventually a Mame arcade cabinet will be as big as the controls, speakers and screen, so you can spend more time playing than building it for other folk who can be arsed to bother to play it after all the hassle.
Good and a shame at the same time, like when credits to continue came in and made games about cash and not skill.
Pandora mk2 will feature a ´quarter slot´ that renders all save states and memory card saving void. Then we can attract the game history giants and have a re-union.
