Steps To Reproduce	Coin up & Select your Ship During the launch sequence (Plane taking off) Hold down a direction You should notice a freeze during the level transition (when the screen fades to black/loading the next level)
Additional Information	Maybe a Real Hardware quirk or regression from the Toaplan 2 driver split?

And it doesn't have the encrypted NEC CPU, so if it's an unintended regression (not caused by a bugfix), it's none of those at least. I don't see it happen on PCB videos.
No.22845 hap Developer 1 day ago	https://github.com/mamedev/mame/commit/d1cbfd7909c95cb8e3edfd0132ee113d11f13c99 This brings it back to how it was in 0.272, but as I said, it still does a brief stutter. It's easy to see from PCB videos that the longer stutter does not happen there. But the shorter one, I don't know.
No.22846 Haze Senior Tester 1 day ago	this was definitely unintentional, I didn't mean to change the logic of that function at all (dogyuun is very sensitive to it)
