It is unclear to me what "being in check" means if you have two royal pieces that have to be captured both, as these could never be captured in the same move. Normally "check" means you are one move away from losing. But in variants with extinction royalty you can ignore attacks on the royals when you have more than one. So if the Prince gets attacked, must this be resolved, or can you ignore that? And if the King gets attacked while you still have a Prince? What does it mean that "both are checkmated"? Pieces can be checked, but checkmate or stalemate are properties of the entire position. It could be that both Prince and King are attacked, neither of these can move to a safe square, and the attackers cannot be blocked. But that the Prince can capture the protected attacker of the King. This loses you the Prince, but resolves the check on King.
I see no justification for using piece symbols that normally designate other pieces. Especially if these symbols are indicative for the move, such as the Crowned Bishop. Why intentionally sow confusion in a variant that has so many pieces already?
