My fork of betzaNew.js seems to be working now. All I changed was the line assigning the value of diag.innerHTML in the CreateAnchors() function. Here is the changed line:

diag.innerHTML = '<div id="container' + dnr + '" style="flex: 1 0 auto"><div style="flex: 1 0 auto"><p id="message' + dnr + '"> <b style="background:' + hicol + ((files + (rank1 >= 0))*sqrSize < 400 ? ';font-size:smaller' : '') + '"><a href="http://www.chessvariants.com/invention/interactive-diagrams">' + startMessage + '</p>' + '<table id="board' + dnr + '" cellpadding="0" style="border-collapse:collapse' + (background ? ';background-image:url(' + background + ')' : '') + '"'+ (coords < 0 ? ' border="1"' : '') +' oncontextmenu="return false;"></table></div><div style="flex: 1 0 auto">' + (pieceInfo != '' ? pieceInfo : ai == 2 ? '&nbsp;&nbsp;&nbsp;&nbsp;<i>This diagram plays chess!</i> ' + aiMessage + aiBar : '') + '</div></div>';

First, I grouped everything inside of two divs, so that I could use CSS flex to display the pieces alongside the board. To make sure everything worked right, I tested it on this page with some CSS modifications to show the pieces alongside the board, and I tested it on the Ultima page without any new CSS modifications to make sure there were no problems.

One problem I encountered on the Ultima page was that the board would shrink when I added the extra divs. Since Web Developer Tools showed me this was due to flex-shrink being set to 1, I added the style of "flex: 1 0 auto" to each of my new divs, which allows growth but forbids shrinking. With this change, the board displayed at full size. I also tested how much I could reduce the size of the board by reducing the window width, and it was the same as the official betzaNew.js script.

Another problem I encountered was that if I changed the display of the idiagram element to flex, the bare interactive diagram code would show up if JavaScript were off. To fix this, I added a container div around my two main divs. Since this div is written by JavaScript, I can freely add CSS on the page to change how it displays without causing any code to show up when JavaScript is off. With this done, the only CSS I needed to add to the page to make things work was this:

<style>
  div#container0 {
    display: flex;
    flex-flow: row wrap;
  }
</style>

The container0 id refers to the new container div. With this CSS, the piece table shows up on the right side of the board when the screen is wide enough. When it isn't wide enough, everything displays in a single column like it normally does. In tests I've run, the new divs do not stop anything from working, and they do not change how anything looks without the addition of the CSS code mentioned above. So I recommend merging this with the main betzaNew.js script.
