Thanks for the info. It has been a long time since i updated, so i should read up a little more. I was just scanning the forums and found no mention on either topic.
I played berzerk constantly, so i know that otto appears too soon. On the first board it was like 1 minute before he apeared, and the 2nd board it was like 45 seconds and so on (this is in the arcade on the actual machine). It's not important, just that it makes it a little harder. Thanks again for the info and the "welcome back"
