actually, you've been replied on the other board... but it took a few days
and the answer is: you cannot. no device or dipswitch can be added on a per-cart base (yet), and therefore no switch on the cart can be simulated yet. it's the same problem that forces MESS to have separate drivers for console carts with a CPU on the cart itself (see e.g. snessfx, gensvp etc.)
it's something we are slowly getting closer to, but we are not there yet.
