About This File
Here is the 1979-86 NBC Overlays. All you need to do is copy the igonly.big file into your data/frontend folder, but make sure you backup your current file first.
I don't have the nice original backup proof that I had for the 1971 overlay, but I did do the research in the NBC site and a few others, to mention that this version can be used from 1979 to 1986 give or take. If I can find anything like the 83 ALCS or any other games for sure in that time frame that sports the NBC logo, I'll fit them in for a screen shot.
Thanks,
