Depending on your philosophy on emulation, "correctly" could be something of an overstatement.

This doesn't at all cheapen what they've achieved, but the code in question doesn't emulate the bubble memory management controller, which is believed to be some sort of MCU. It's more of a high-level simulation of the bubble memory system rather than emulation itself.

It's somewhat akin to various drivers where MAME had a 100% correct simulation of a given protection MCU: From an end user's perspective it's functionally "there", but there's still work to be done on the team's end to bring up the level of hardware documentation and accuracy.

Not trolling, just pointing out a few caveats regarding this admittedly impressive achievement.
