DeSmuMe Problem: Black BG Color

[Ploaj]

Try this code for changing the BG color:
0600C000 DDDDDDDD
0600C004 DDDDDDDD
0600C008 DDDDDDDD
0600C00B DDDDDDDD
0600C00F DDDDDDDD
0600C013 DDDDDDDD
0600C017 DDDDDDDD
0600C01A DDDDDDDD
0600C01E DDDDDDDD
0600C022 DDDDDDDD

Otherwise, just use Tinke.
Here are the files you want to look at:
ncl - Palettes Offset: 8
ncg - Tiles Offset: 8
nsc - Map Offset: 12

Viola, background.

This is all confusing.

How does that work in Tinke?

Is there some sort of video tutorial or screencap-by-screencap step process?
