Your message is a little unclear. Are you trying to make it so that the colors and graphics don't change after beating the Special World? Those changes happen if you beat level 125, which is FUNKY. You can alter which level causes the change from the Overworld Editor
. Go to Overworld > Change Special World Levels. A box will open with 3 fields: "Change Overworld Color if passed level", "Change Koopa Palettes if passed level", and "Change Sprite Graphics if passed level". By default, the level number in the dropdown menu is 125. If you have level numbers in your hack that are unused, then you can set the change command to one of those unused levels so that the graphics and colors won't change.
