I have a Samurai Spirits pachislo that is giving an unusual error. I'm not sure where to begin with this.
If you stop reel 2 or 3 first, the LCDs will both cut out (the upper LCD shows an !) and there is a buzzing error sound. Gameplay does not stop and everything continues normally. Once you start a new spin the screens come back. If you stop reel 1 first, then it doesn't matter if you stop reel 2 or 3 next, it will be fine. The buttons all work and stop the reels properly, it's just not tolerant of you not stopping reel 1 first. Any ideas?
