For now, at least, c800–cfff is always built-in ROM.

Otherwise I probably need to extend my c3 logic to cover the other built-in cards (?)

For the record, the ROM thinks it finds some Smartport devices and then attempts to talk to them. Since none is present, it blocks forever.

It appears that ROM 01 now fails because reading the disk interface register doesn't do as expected. ROM 03 starts hitting what should be the IWM and dies in a surplus of logging.

Completes logic for pixel framing. Well, mostly; this doesn't yet allow for auxiliary-using II modes being off to the left.
...
The perceived effect though is that a frame appears and then freezes. So a clocking issue may still be afoot.
