DS 16

This "demo kiosk unit" was always a mystery to me.
At first, I think it was some sort of "5V line switch" but then I discovered it was connected throught the expansion port (same as MegaCD).
why is it connected through the MCD port ?!
on the available doc, the cart is defined as a "slave cart" not as a main cart with logic which could load game
The only reason I saw was : the DS16 loading as main hw (for slave /cart to 1), loads the game on slave cart then reboot with slave /cart to 0
but a pic of the cart broke this idea (http://nintendoage.com/forum/messagevie ... did=141994) : no memory nor logic on pin 32
so, again, if the DS16 redirect the selected cart pin to the Genny cart through the slave+cable, why on earth is it connected to the MCD port ?
I know the DS16 also include some kind of timer which switch the selected game every X (?) minutes but it doesn't explain it!
the DS16 is a rather complex as you can see on this assembler' thread

(sorry, assembler seems to still be unavailable)
so what do you think it REALLY does, which could explain the MCD port use (and i really hope you won't say "because of the 9V lines")
On a side note, I saw a ferrite on (almost) every DS16 pics I found, over the DS16<->slave cart cable
How long could be the cable with a ferrite ? i though it was very bad idea to use this kind of cable (which runs the data and address lines it seems)...but not the real reason (noise?)
I ask because I'd like to do it on my dev unit but don't know if it won't create problem...
