nope, it's not hard, in fact NOZ support path

just put your skin on seperate folder
and then change your noz.ini setting to something like his
Quote:
[no$gba-4-DS black_Skin]
BMP=dsskin\skin1.bmp
|
BMP path use relative path based on where you put noz executable and noz.ini

in that example, i put my skin on a folder called dsskin ^_^
