Cool!
It's funny you posted this now and were playing tonight, because just yesterday I started getting "serious" about learning Junior.
And now that I know a little more about the game, I've spotted another difference in gameplay with
my "Hard" kit ROMs. There is NO safe zone on the chains board. The birds can fly down a "notch" further, meaning that they have coverage over the whole screen. Ugh! I think that might make my board virtually impossible, because using that safe zone is critical, isn't it?
I wanted to save-state practice it in MAME, and then I remembered that this kit isn't emulated...
