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.

Switches the Electron to JustInTimeActor video.
Also reorders template parameters; I think that specifying a different time base is likely to be more common than using a divider.
