How to make pieces royal?

I'm trying to create a variant but I'm NOT able to make the amazon royal in the edit position tab. Can someone please help?

It's under "More Options."

you enter the coordinates of the royal piece in the "Royal Piece" box.

You have to put the coordinate of piece you want to make royal.
Note that changes are applied after textbox loses focus. Also, don't forget to follow the colors.

ok i was wondering that to thanks

There should be a pinned forum that explains all the things about making games. Or is there one already? I have no clue.

well this helped and now i can make royal pieces

also if you don't know the coordinates you can press "k" and there is a coordinates helper

* If keyboard shortcuts are enabled (in settings).
** see help tab ("h") to learn more.

oh so i accidentely hi k in the middle of a game and i kept seeing coordinates everywhere i moved
