Was just coming back to ask if you meant the sprite flickering effect when larger bosses are taking damage and/or moving around quickly. Yeah, IIRC that happens on MVS, too. I always put it down to Video System weirdness, but maybe that's my Micronics-phobia talking, haha. (they helped out on the first Sonic Wings, apparently)
Now that I think about it, rather than going to the trouble of deleting your ACA system data every time (and thus resetting all your display, control etc options), it'd probably work just as well to perform a single delete, then as soon as the "Neo Geo" bootup loads, create a savestate (the "Create Interrupt Save Data" option).
As long as you then restart the game by using the "Back To Title Screen" command, rather than "Game Reset" (this will wipe the savestate), and as long as you do this
before entering your name at the end of the credit (this will wipe the state, too), you should be able to get fresh bootup conditions every time. Just gave it a go, seems to work as described. Like all ACA releases, the state will remain in place no matter how many times you start and exit the program, just avoid Game Reset or entering your name.
Related: When I'm working on a trouble spot in a run, I like to set the state for practice, then use the Hi Score mode for full runs - HS mode will always put you at the start of a credit, without exceptions.

Has anyone else noticed that it can be inconsistent? Sometimes it will save your scores and other times it won't? I wonder what actually triggers it to save.
Strictly from layman's perspective, I get the feeling the HS table data saves after you enter your name (this is where the games will ask if you want to upload to the leaderboards).
