Considering I've done most of the other Sharp X68000 Gradius games by now, I figured I might as well tackle this one.
Honestly, I don't think there's much I really have to say about this game. It's Gradius II on the X68000. It's very close to the arcade version aside from a few tiny differences (such as a lower screen resolution, akin to the PC-Engine version). I will say that the Configuration menu gives you an autofire option, but the Hz rate is so slow, you're better off continuing to mash the fire key anyways. Also, I'm not sure if there's supposed to be that much slowdown.
You can stop watching after Loop 1; I didn't really care to make high loop progress with this game. I just wanted to get this one done and over with so I never have to worry about playing it ever again.
