Now I wonder how the test it ? Is it on a software emulator on modern equipment or do they have a Voyager replica ?

That would be an interesting project, I assume a lot of not so young engineers will want to play with it, as a hobby. Also if that project exists, I'm sure that someone will try to port DOOM.

I believe they have both.
Simulators for the spacecraft and replicas for some bits of hardware.
What they have is surprisingly fragmentary. For the recent software issue, they had to be very conservative in what they changed because they aren't 100% sure about the details of the ISA on the actual spacecraft (due to amiguity between different revisions of the wiring of the CPU), and so they don't really have a simulator they can trust.
