I have just set up a new hyperspin system with version 1.4 (rocketlauncher). There seems to be a bug which i think i also had on earlier versions of hyperspin.
When i start a game with the button and at the same time use the arcade stick and jerk it around (move it fast left/right/up/down) the game starts but the hyperspin theme/video seems to stay active on the background. You can hear the sound of the video playing while the game is also active.
Why is this a problem?
