XGA changes of the day (July 12th, 2025)

Browse Source 
1. XGADemo now displays the correct colors through implementation of the palette sequence order in bit 2 of reg66 (Palette Sequence) of the XGA  ports and no longer hangs DOS when displaying the demo per interrupt r/w ports implementation.
2. And some more checks for more patterns needed by some software.
