Another enjoyable video. A JPEMU one might be worth doing sometime in the future, as well, as there are probably some exclusive on that as well.
I'm not sure I played Super Star for real. I certainly don't remember any clear memories of playing it.
Scorpion 1&2 was around quite sometime when you consider that Jackpots started at £4 and ended up at £10, although I'm not sure any actual £10 jackpot machines where built on it, just upgrades from £6/£8 to to £10.
