After a generalised version of Elephant chess . . .

The aim is to be first to capture all three of your opponent's(') king, general, and king general. At the end of the game, victory points are awarded according to the proportion of kings captured on each side, so if you win but lost your king, general, or king general, you'd get 3/4 victory points and the opponent will get 1/4 victory points. However, as in Xianggqi, if the general was captured via a flying manoeuvre, then a quarter of the points from the general capture that would have gone to the capturer instead go to the captee. This makes the victory point allocation deliciously more sophisticated! (For example, if in the same scenario as earlier you actually capture your opponent's general through a flying manoeuvre, the the victory point allocation for you is 11/16 and for your opponent it's 5/16.)

When the game starts, the first 12 moves for each side are placing any of 11 pawns on the row second from the centre, then replacing a chess bishop with a shogi one. Rules for all the pieces are essentially exactly as they are in Xianggqi, Shogi, Chess, and Draughts/Checkers including the Shogi drop rule, and shogi pawns promoting when they reach the last three points.

When the chess king moves out of it's starting location for the first time, the shogi king general is dropped onto the same starting position the King moved from. The chess king can castle with the xianggqi chariot or chess rook according to chess castling rules! After castling, you can choose to switch the positions of the chess rook and xiangqi chariot.
At each turn, instead of moving a piece, a player can place a baduk stone, and again the rules are the same as in baduk. Once on the board they can be captured by other pieces in the same way as every other piece. However, together your baduk stones can capture your opponents pieces or groups of your opponents pieces, including baduk stones, in exactly the same way as in baduk. As an example, a chess piece and a baduk stone of the same colour that are orthogonally adjacent to each other, can be captured by six stones of opposing colour, exactly as in baduk. The only restriction on baduk stones is that they can't placed down if it blocks a check made by the opponent on their last turn.

The only significant difference is that here isn't an unlimited supply of pieces for chess pawns to promote to. Pawns only promote to pieces that have been captured, and two of the hybrid chess pieces start off as captured, while the queen starts on-board.

Black is Sente and White is Gote, with players colours at the start of the game determined as in Shogi or Igo, the rules for deciding who does nigiri and furigoma is the same so in essence that player decides which one is done.

Generalised Elephant Chess, Xjianggqi, and Chesshogi, Xianchess, Xianshogi?
1-Maybe a better version, Okay each page shows one of both sides of each piece, and the general can start in any position shown.
2-All pawns start as 卒, and can move up to two side to side before crossing the river without any issues, and once done it flips from 卒 to 兵. You can move a third side-to-side before it crosses the river, but if you do and the opponent doesn't and the game ends in a draw on the board, your opponent will get 0.5+ (0.5/∞) board points while you will get 0.5- (0.5/∞). In other words, they'd have 1/∞ more than you and so win the game.
3-And this is the rule I'm most satisfied with. All elephants start as 象, You can move up to one elephant across the river, or use the special Janggi move, and from then on that elephant flips to 相 and moves as in Janggi.
4-The Fire Cannon 炮 moves as in Xiangqi while the Stone Cannon 砲 moves as in Janggi and they can start the game on the left or the right, but the second player to place pieces must maintain diagonal symmetry. Each piece has both characters, one on each side, in case players want to play only Xjiangqi or Janggi, or Xjiangchess, in which the canon flips after each move, or Xiangchess or Jangchess.
5-Each general can start as in Xiangqi or Janggi. The Janggi rule for generals leading to a draw applies, and the Xiangqi rule for the Flying General manoeuvre also applies, but if you win this way, it's only by 0.5 a board point instead of 1 (you'll get 0.75 board points to the opponent's 0.25, instead of 1 to 0), so obviously in a winning position in a multi-game match one may choose not to use the Flying General.
6-Players place each piece alternately, and then this continued with the player placing the first piece also making the first actual game move. I think in Shogi and Chess, the lower-skilled player should always start first, or in a match of multiple games with the player having the first move alternating each match, the weaker player should play first in the first game. However in Xjianggqi the player who sets each piece up first is at a slight strategic disadvantage, and this is compensated by them also moving first. The ability to switch cannons for horses as in Xiangqi is there, however the ability to switch pieces as in Janggi are only allowed in multi-game matches, or in other words, the setup for the first game in any match should be the standard Xiangqi setup. From the fourth game on, any setup along the first row is allowed.
7-If both players agree, the rules for the pawns, elephants and cannons and position setting can be changed, and in this way the game can essentially either the Korean or Chinese versions.

In Chesshogi, on a Shogi board are placed Chess Pawns, Shogi Fuhyo, Chess Pieces, Shogi Pieces. The first eight actions are the players alternatingly placing these in any order; on the board, on each selected side, instead of shogi fuhyo there are four chess pawns, and instead of the shogi pieces there is the queen and then bishop, knight, rook, in that order from centre as in chess. Then, on a Chess board, the queenside pieces are replaced with Shogi Pieces in the same order from the King general in Shogi. In Chess and Shogi, the weaker player should always be first to move in a game or match. In Chesshogi, the weaker player decides who goes first. For players of equal ability Furigoma is used. In Xianchess, the placement of the chess pieces on the xjianggqi board is the same, but with the type of cannon and elephant, determined by whichever is the player of any elephant chess, or if both or neither are, the less skilled, or if both are the same skill, the younger one. Xianshogi works the same as Chessogi with Xjianggi and Shogi Pieces and Pawns, however in addition the bishop and rook being placed behind the canons in their respective shogi places, then on a Shogi board the same essential rules also apply but here the player decides which two of the rook, bishop or two canons to start with and which two to have in hand that cannot be dropped normally but instead automatically must be placed in the position as soon as the square is empty, after which their use returns to normal.

Draughts aka Checkers
Because there are many variants of both Atlantic Checkers/Draughts, I left the fifth page blank for you to create whichever draughts checkers game you like using tables and the checkers/draughts pieces.

Weiqi/Igo/Baduk and Tables Games
In Xianshochess, a West African mancala board keeps the 24 stones each player has, with mancala being a proto-member of the tables family of boardgames that includes backgammon, and interestingly West African Mancala has a legend very similar to ranka. Because there are many variants of tables games, I left the fifth page blank for you to create whichever tables game you like using tables and trianglesand go stones. Similarly most people here have or can get a go board editor already.
