Haven't read the rest of the thread yet as still trying to solve unaided. Just popped in for a moan. Have 3/4 of the grid, and the three normal answers. Think I know the method for entry for the three normal answers. However, much like the other puzzle that used this device earlier in the year, there seem to be literally tens of different options for each of these. So far only one has an option that matches what I have in the grid. For the other two I have painfully decoded about 15 examples each from the internet, none of which match my letters. This form of entry should be banned in my view.
Plus I have the name and it is associated with a genre I detest heartily.
Right, rant over, back to the puzzle.
