So, I got a really nice Dirty Harry a couple days ago. I bought it and transported it about 250 miles in my SUV. It worked fine except the gun didn't work properly. It was never available to use at the start of the game or any other time.Then I get a 76 and 77 switch error. I checked the switches but one seemed weak so I changed it out. Still nothing. I get up this morning and go to turn the game on and get a U22 error.Game wouldn't start. I shut it off and restarted it and it came on with no U22 and no switch errors and the gun works PERFECT. What the heck does that mean? Any suggestions.
