Screen has artifacts on boot up. During game play they will be removed by explosions.

ARII has been rebuilt, +5v on the board.
All chips pulled, cleaned and re seated.

Pics!

Thanks for looking!
 
I am not sure what is wrong with your game. I kind of think I see good hardware because it can erase the artifacts. I would be looking more at a programming anomaly from the rom chips that I think 8 9 10 11 if I am reading it right just took a quick look. maybe bad program i nrom or maybe some of the decoder chips not working or ram chip has bad path to it. it kind of seems that the program is not generating a screen reset color in those areas when the game starts but can as the game runs
