I have read what Fergus Duniho wrote about OR-AND Shogi, Xorix Shogi, and Assimilation Shogi. From what I can tell, not all pieces used in Xorix shogi will occur in OR-AND Shogi.
Here is a way to number these kind of variants. This is by giving a sixteen-bit number:
Bit3-Bit0: These specify what kind of bitwise operation to apply to the new piece on board. Each bit set corresponds to the bit set according to the condition corresponding to that bit: bit0=if neither piece has that ability, bit1=if the capturing piece but not the piece being captured has, bit2=if the capturing piece has not but the piece being captured has, bit3=if both pieces have.
Bit7-Bit4: These specify what kind of bitwise operation to apply to the new piece available to drop.
Bit8: If set, indicates that all pieces always have capability one space straight forward.
Bit11-Bit9: Specify kind of promotion.
Bit12: Rex inclusive: Changing also applies when king captures other pieces. The piece is still the king regardless of how it moves now.
Bit15-Bit13: Specify what happened if the piece on board or off board becomes one that would have no available moves (if Bit8 is set, also applies if a piece would be a shogi pawn).
List of kind of promotion:
0: Xorix Shogi promotion.
1: No promotion.
2: When it reaches a cell it can never move from, it can and must change so that it loses all moves it currently has and gains all of the other moves. You cannot promote in other circumstances.
3-7: (Not yet defined)
List of what happened if a piece would become no moves:
0: You get no piece available to drop. If the piece on board, becomes permanently destroyed.
