As I say, it's not a biggie, unit still works fine.
But the "Push Run Button!" message on screen appears on the top as well.

I've tried different AV cables, as well as powering the system on and off.
And tried it with a couple different PC Engine units, as well as the CoreGrafx variety.
Nada, this double message persists.
So only a small issue, but any ideas as to why it would do this?
Is this CRT television?
