The modded dlls come from dmginc's post on this thread, but the original author uses a wack file sharing site, and I've done a slight mod, so I've reuploaded it on the forum. I've also uploaded patches for 6.3.0 and 6.2.2 to this post, but they can also be found in the previous link.
In the attached .zips are the dlls for getting QT 6.2.2, 6.3.0, and 6.3.1 based applications working. Copy and replace any files in the application directory, and it should work. If you have any problems with QT 6 applications that don't have specific posts in this category, reply and I may be able to help.
