I was about to transplant a different board into this case, but actually looking at it, it seems like the I/O shield is built into the chassis.

its a punch out, few snips and its out

Even if that pops out, that's not going fit into a different case, is it?

shape is standard, might need to use tape to secure it 😀

Genesis is a normal DB9.

Many vintage serial mice used the same kind of molded plastic plug.

It's (genesis controller) physically (and mostly electrically) the same as an Atari Joystick.

There's a community breakout board for TI 99/4A microcomputers for dual joysticks that's basically just some passives and some db9 connectors.

I can confirm that genesis controllers fit fine.

This is good information, thanks. I'll reply again when it's delivered.
