Baby steps: apply Z80 state.
...
As far as it currently is. Since SNA is leaving the PC at the default of 0x0000, this currently has no visible effect.

Basic sketch for state snapshots: an extra field on Target.
...
I think it doesn't make sense for states to own a target as that complicates the concept of Media. Plus they're distinct because it makes sense to have only one per Target. Let's see how this pans out.
