Apocalypse
Is this question directed to me?interesting finding. Is there any specific type of board that must be used for this version?
Are you talking about the C&D conversion?
If so you need a B-01/B-21 C-board, then with file manipulation (merging/splitting/interleaving/de-interleaving) and by handcrafting a new PAL you can use any B-board you want.
