Is it something the MD does automatically when the expansion port is used and the cartridge detect pin is low or does the CD bios do it?
Sorry if this is a stupid question.
How does the cartridge slot get mapped to 0x400000?

Now that I think of it, smart address decoding coupled with selective driving of #CART is almost certainly how the Everdrive can loads a CD BIOS from the cartridge port.
What does db stand for? Well that's an excellent question...
