Hi there!
I thought of a solution where the the input signals would flicker. So you could utilize "4 kind of any controler" at once. On frame you'd read one controler, next frame the second. And this for both ports.

s. I think you have to sample all controllers every 60th of a second to avoid missing any transient signals. This is especially a concern for the driving controller that already messes up if you twist it too fast.

Any real multitap would need to respond to commands very quickly so that you could sample each controller in one very small block of code with minimal busy-waiting so it can all fit in one VBLANK.
