I don't know if this applies to the Korea map specifically, but load times of maps in general can be reduced considerably if the ed maps are set as indexed color instead of RGB.

How is this done?

Using an image manipulation program, such as photoshop or Gimp.

I use Gimp - Open the ed map files, then from the menu select: >image>mode>indexed

a box will pop open -> set to optimum palette in 256 colors with dithering set to none.

press the "convert" button and then >file>save as with the original file name - then a window opens and here make sure to uncheck RLE compression, then hit save.
