Quoted from Paul_from_Gilroy:I don't think this has been reported before. It's either a bug, or something the programmer did intentionally. Either way, I think it should be fixed. In my GB Premium, during gameplay, the pop-bumper flasher (the big round insert) is normally-on instead of normally-off. When the ball hits the pop-bumpers, the flasher flashes off (instead of flashing on). Just the opposite of what it should do. If it's intentional, I guess it's clever. Problem is, the split-second "off" flashes are a real nothing-burger, barely noticeable. The rest of the time, seeing as how it's a white flasher and it's almost always on, it adds to the bright playfield illumination (which is the last thing GB needs).
I noticed that as well... I thought there was a problem with the slingshots.... Hope they will fix that behavior.
