No it does not appear the emulator is doing this.  There are no references shared between the PIA module and the GIME module.

I can see the software running on the emulator is explicitly turning of both GIME interrupts and PIA interrupts!!!

This makes no sense as it should stop working on real hardware as well. So I suspect there is another unknown mechanism the emulators know nothing about.
