Alright... interesting, I'll check it out as soon as I can. Yeah stage 2 (not 100% sure) and stage 3 have only have marginal differences from the original, just an enemy or two that don't shoot bullets. It's good to see that the skill verdict is being worked on right now . Also I'm assuming there's been a reduction of input lag as well?
Okay, I found them in stage 3. Not one or two, perhaps ten.
Also, they not only don't shoot bullet, but also have no hit judgement.(just have charater's bullet hit judgement.)
So although you collide with them, you will not die, if you didn't die by other bullets.
I don't know why they are happen, so fixing this would take some time.
And input lag, can't be reduced.
Because of accuracy, original code get one input per one frame, in PC98 version's speed.
And I think it would be not good to fix this.
