Consolized 2 slot help.

Your gonna have to excuse my ignorance here.
Is there any way to play jamma boards through this fella. I assume there is a mini supergun in there. Probably a stupid question but please.
Oh and on the scart lead there is a little knob with 100 and 200, so you can switch between them, Whats all that about.
If anybody has a link or anything to an explanation of dipswitches and suchlike I would be very grateful.

No mate, you won't be able to play JAMMA boards with a consolized MVS. The supergun that's built-in wont work with anything else. Unless of course you can design an MVS to JAMMA adapter, which I would imagine wouldn't be very easy especially with kick harnesses and stuff.
