So for the record, is both colours allowed to be moved? And does both or only one king need to reach the other side?

@Adam - This is calledRetrograde analysis, and the standard constraint is that you are supposed to figure out how the position was arrived at via the normal rules of Chess - that is, alternating white and black moves, with white moving first, no unannounced checks, no failures to escape check, no illegal moves, and so on.

Legally:
34 moves
Illegally:
16 moves if counted normally: 31 moves from standard set-up position into the layout in question (14 pawns to destination + 2 pawns outside, 12 other piece outside + 2 queens to position + 1 king out of check). Which is move each side both pawn except 2 (1 of each side to the outside of the board) and all other pieces except king and queen outside the board.

So, far, I have been able to get MOST of the pawns in their place. It’s just that the center is so full of pawns that it’s nigh near impossible to switch them. I will look into other ways such as going around the center in some convoluted way.
PGN viewer
UPDATE 1: From what I can tell, the wanted position is actually impossible t get. But you can have a very SIMILAR position, as seen in this game. I will work on getting to be as fast as possible.
PGN viewer
UPDATE 2: I have found an even more similar position whilst finding an even quicker version. This version is faster, yes.
PGN viewer
UPDATE 3: Another attempt, without the annoying spaces in the above game, and only a few moves longer.

Legally:
34 moves
Illegally:
16 moves if counted normally: 31 moves from standard set-up position into the layout in question (14 pawns to destination + 2 pawns outside, 12 other piece outside + 2 queens to position + 1 king out of check). Which is move each side both pawn except 2 (1 of each side to the outside of the board) and all other pieces except king and queen outside the board.

Credit to @Mukyuu for making the original game. I managed to get it down by half a move.

So, far, I have been able to get MOST of the pawns in their place. It’s just that the center is so full of pawns that it’s nigh near impossible to switch them. I will look into other ways such as going around the center in some convoluted way.
PGN viewer
UPDATE 1: From what I can tell, the wanted position is actually impossible t get. But you can have a very SIMILAR position, as seen in this game. I will work on getting to be as fast as possible.
PGN viewer
UPDATE 2: I have found an even more similar position whilst finding an even quicker version. This version is faster, yes.
PGN viewer
UPDATE 3: Another attempt, without the annoying spaces in the above game, and only a few moves longer.

Yeah I know, this answer is a bit sloppy in organization atm. Is you can edit it to get a working replayer in for both games, please do do that.

So for the record, is both colours allowed to be moved? And does both or only one king need to reach the other side?

@Adam - This is called
Retrograde analysis, and the standard constraint is that you are supposed to figure out how the position was arrived at via the normal rules of Chess - that is, alternating white and black moves, with white moving first, no unannounced checks, no failures to escape check, no illegal moves, and so on.$endgroup$
