My son and I are both loving this game a TON (he's 12).
We first played on an NTSC A1K, but during scenes with lots of moving elements it would sometimes slow down a little bit. So we moved over to an NTSC 16Mhz A3000 and it plays like perfection.
Two things we've noticed, that you might want to know about.
At the 2nd boss, there appeared a vertical graphical glitch. See here:
You can see it in action when it reveals itself here:

Also, at the bottom of the screen where the ship counter is located, the entire bottom of the screen is missing a few rows. Thus you only see ½ of the ship down there with the number next to it.
Oh! I tried to move the MOD files to my machines but Hippo wouldn't play them for some reason. I hope to figure that out later...
Other than those 2 minor graphical issues we're have a total BLAST! I got both the digital and collector's edition. Thanks for all of your hard work!
