Hacking Global Config Settings Questions

[Zenith94]

I found this is the Global Configuration Settings in the DSystem folder for my n-card:

[SAVEBACKUP]
; set the option of force backup curren save to MK5 after turn on nds,default set to 0, mean don't force save after turn on --- 1=YES , 0=NO

What does it mean?




Also which color, BOX, SCROLL, BOT, etc, changes the Rom Icon background transparent color?
