Just wondering why he wouldn't submit a game score before playing another, your friend must be a masterful gamer addict
I am going to see if this happens in my arcade and I'll let you know and if it does try and find a fix for it. However I doubt it can be fixed as we get a similar problem when my husband and I play same game in a tourney and submit it disqualifies and thinks we have played as I believe it to be an IP issue and confuses the code on where it should be submitting.
