Thanks for testing! At some point, it's also a distinction without a difference for me. A 100% faithful reproduction without the original ROM or hardware architecture still works like an HP-15c from my point of view. Similarly, an emulator with the original ROM might not emulate the CPU perfectly.

One very certain litmus test for CPU emulation would be if the "on+y^x" trick, which (inadvertently, it seems) allows access to internal memory, worked, but all the apps I've tried just don't seem to accept pressing "on" and any other key at the same time by way of how the keyboard is implemented. (It's not really useful for the function of the app, so it's hardly a fault.)
