I've never looked up on this, but how do you change the colors of the little blocks that appear on the signon screen, you know them yellow and green bits sayin if you have a joystik and how much memory you have left, etc..
Here ya go:
Open WL_MENU.C, find the line that says
::: CODE :::
#define MAINCOLOR 0x6c
#define EMSCOLOR 0x6c
#define XMSCOLOR 0x6c
#define FILLCOLOR 14
Change the value of MAINCOLOR, EMSCOLOR, and XMSCOLOR to be whatever palette color you want them to be.
Then change FILLCOLOR to be whatever color you want the joystick, etc fill color to be.
I did this awhile back, but I think that's all you have to do.
