Okay, okay... Again, you have to set the ACTIVE subscreen information via Misc->Subscreens->THEACTIVESUBSCREENYOU'REGOINGTOUSE.
From there, select 'Use big triforce pieces, and the ZQ also has a Large Triforce Pieces frame that is not selected by default. You must select that by clicking on the frame and finding the proper frame on the tilesheet.
There is another box to the right of that that is a single tilespace for selecting the actual triforce piece itself.
If the active subscreen (on pause) is also the passive subscreen, you obviously didn't edit and select the ACTIVE subscreen.
To get the desired result then, you must select the proper ACTIVE subscreen for your DMAPs, either before or after you've edited it to cater to Large Triforce Piece graphical representation.
