This is the farthest thing from the truth on how the PBC works. If you open up a PBC you will see that it is nothing more than a pins-converter with a small bankswitching chip on it. The Genny is actually reconfigured to act as a SMS! The Z80 used for sound is pressed into service (along with its 8K of RAM) to act as the "emulated" SMS' Z80 and RAM, and the graphics chip is put into emulation mode. So the Genny is really 95% backwards compatible with the SMS... the 5% remaining is the need for the bankswitch chip (it is only 20 pins). In fact, some pirate Genny carts run in SMS mode.

For what it's worth, I sawed the end off of a PBC trying to get it to work
with my Nomad (the two physically don't fit stock) and ended up with, yep, a
pile of stinky sawed plastic and a crummy looking PBC that later found the
trash.  :^(  So here's first hand experience that it didn't work in the

The PBC does not work in the Nomad since a couple of the lines from the chips to the board edge are missing. (And you would've been better off removing the PBC's guts from the plastic case then trying it :-)
