so here is a small example of what you can do with these
this is gamecommon.OJSON viewed in notepad++

you can turn off the underarmour and statefarm wipes by changing them to false
this doesn't skip the audio and the segment but the overlays of the graphics will be gone
(except for that stupid blurring effect in the UAwipe)
Now if you see something of the type "PACKAGE"

I think that means that package of overlays is also nested within it
so otfcoverlays.OJSON is a file itself but it is included within the gamecommon package

see what you can come up with
One thing I hope to get to work is that in 2ku the scorebug disappears while shooting free throws and I think it might be based off of ScorebugFlyouts within practice_scrimmage.OJSON
Another example that was successful was in offlineblacktop.OJSON the NewScorebug overlay is set to false and BlacktopScorebug is true so I just changed those 2 and got the normal scorebug in blacktop to show instead
gamecommon.OJSON will be the largest file with the most options so be careful with editing it and don't be surprised if the screen is blank for a moment if you had turned something off
