I have to display my SCORM packages in the same window as Moodle.

The learning materials in the packages are designed as fixed width (800px).

I was expecting the Stage Size width control to behave like the height control on the iFrame, and would centre align on the page.

However the width control seems to have no effect at all on the iFrame. If that's deliberate it shouldn't be available when choosing same window.

The workaround is to centre the modules using CSS within the modules.
