Regular players/Devs might have difficulty getting to Level 6, much less that Boss.
Hopefully this isn't too much of an ask but if you do play this game again in the latest release - make a save state before the 6th level boss.
Should it Fatal Error during the battle, it will be so much easier for a Dev to be able to zero in on the issue.

I've acknowledged for now.

That i can do but it will take a will because its Gradius. I didn't even know savestates worked or were stable with Gradius IV

Ooh yeah, I remember also getting this back when I tried a playthrough when I was newer to mame. The other issue this game has is the graphics background corruption at stage 3, but other than these 2 things it's so close to being accurate. Happy to see more eyes on this game :)
