All, I'm sure this has been covered (I think I saw it) but I can't find it at the moment. I looked around on the r4 forum but that wasn't helpful. (Did find some cool homebrew, however.) What I want is to customize either a dat file or an ini file(s) so that on the r4 main screen the left game icon brings up my .nds games listing, the middle music icon brings up moonshell or a straight movie player, and the right GBA icon brings up whatever app I want to assign to it (probably iPodDS). In other words I want to change the targets. Do I just rewrite respective ini files?
