Description

When using TAStudio, playback from my marker (6947f) works fine, but playing back from Power On causes an enemy to spawn and desync the run.

ROM filename: Ghosts 'n Goblins (1986)(Elite)[cr REM][t +5 REM][a4][Docs].d64

Research direction

Reproduce the issue in TAStudio using the attached Ghosts 'n Goblins ROM: compare playback from the 6947f marker with playback from Power On. Investigate why Power On produces an extra enemy and desynchronizes the run; done means both playback paths remain synchronized.
